When I was in the 6th grade here in the US (Upstate NY) my science fair project was based on acid rain. My great uncle was a forest ranger in the Adirondack Mountains here in New York and he was one of the first to bring to the public's attention the effects of acid rain on the waterways, wildlife and plant life in the Adirondacks. He was featured on an episode of a children's science show "3-2-1 Contact" in November of 1983.

[@Tatterdemalion-77]

Josh Brown brings back memories. Acid rain was a frequent topic on the news and in magazines for those of us who grew up in the ‘70’s and ‘80’s. Those images were terrifying. Then add in the hole in the ozone and threats of nuclear war...but today kids have to grow up under the threat of climate change. One step forward, two steps back. Or maybe science progresses, politics regresses.

[@charliespinoza1966]

[@pansepot1490]

At least back then politicians moved to solve the problems of acid rains and the holes in the ozone layer, nowadays often the response from politicians is that climate change is not real and scientists are either lying, exaggerating or don’t have a clue.

The calcium sulfate produced by the SO2 flue gas scrubbers on coal power plants is not "just put to landfill" in the US. It is a useful product sold to National Gypsum which uses it to produce things like drywall boards for construction. This works fine when the process is well controlled and regulated, but they started doing the same thing in China some years ago too, where regulations are lax or nonexistent and they didn't take care to remove the substantial amounts of strontium sulfide in the fly ash which made its way into the synthetic gypsum product. This SrS in drywall boards sold to the US then reacted with humid air in Southern homes producing hydrogen sulfide and carbon disulfide gas which was emitted from the product continuously and caused many health problems and severe corrosion of home electrical wiring and water pipes which are made of copper (copper sulfide) resulting in many millions of dollars worth of damage.

[@gordonrichardson2972]

Muonium Wow! Only knew half of that story.

[@connivingkhajiit]

Interesting!

[@asvarien]

I live in the UK and I remember when I was a child seeing huge billboards made of some sort of indicator paper to highlight acid rain.

[@maj21093]

Great demonstration, however, showing the saturated water vapor exiting the Cooling Towers when speaking of the "Emissions" can be misleading to most people. The Cooiling Towers only generate "Steam", on the open side of the cooling system, from cooling the water used in the Cooling Jackets around the Generators, before returning to the system. The towers in no way are directly connected to the Combustion Chamber, therefore they cannot possibly be releasing 8SO3 or 8SO4 into the Atmosphere. I used to work at a Coal-fired Power Plant and the local news channel always tried to mislead viewers into thinking the De-sulfuring equipment had made no changes to the pollution output, however it had. In fact, instead of putting the used Limestone into a Landfill, another company would take it and turn it into sheets of Drywall (Gypsum Board) for construction.

[@ivoivanov7407]

Well it is common practice /by film makers and photographs/ to show cooling towers just because most people associate them with power plants. And it is not easy to show power plant without the cooling towers :)

[@nickfirst7249]

[@JD3Gamer]

For one of my science fair projects in elementary school I (and a friend) tested the effects of acid rain on seed germination by watering bean seeds with a mixture of water and vinegar. We tested 0, 25, 50, 75, and 100% vinegar to water ratio. It was the only science fair project that I worked on that led my friend and I to go onto regionals.

Nonmetals are the most fabulous elements.

[@M1stersupersonic8]

Same thing happened in the Northeastern US. Winds picked up the gases from coal plants in the Midwest, dissolving them into the moisture, and then dropping the acid rain into the Adirondacks. Screwed up the pH of the soil and the lakes, killing forests and loads of fish. Thankfully, they've mostly recovered, but it's still an issue.

[@mgabrysSF]

Calcium sulfate is quite useful and doesn't have to be disposed of. It's a prime ingredient in plaster of Paris and stucco. The hydrates are used in foods like Tofu, cheese products, Flours and more. The power stations offset the cost of scrubbing with the repurposing of the CaSO4. Beats the hell out of gypsum mining.

[@crywhit4619]

I'm pretty sure if everybody saw red rain alot more would be done to prevent these emissions into our atmosphere.

Since Acid Rain got basically eliminated we have to keep an eye on the sulfur content of the soil and use sulfur-containing fertilizers like ammonium-sulfate-saltpeter (2NH4NO3·(NH4)2SO4) instead of sulfur-free fertilizers like Urea.

[@VoIcanoman]

People all knew just how bad acid rain was for the terrestrial ecosystems, but what was forgotten was how bad it was for the animal and plant life living in bodies of freshwater...the relevant experiments were conducted at a place at which I've actually done some work, called the Experimental Lakes Area in northwestern Ontario, Canada. This is a unique natural lab, where individual small lakes and their watersheds can be devoted to particular experiments. Acid rain is just one of the things they tested there (acidifying lakes and monitoring populations of fish, invertebrates, and other kinds of life to see what kinds of changes took place) - determining that it was phosphorous, not nitrogen, that killed bodies of water due to the increased biological oxygen demand was another key finding, in addition to a more recent study that tracked isotopically-labelled mercury as it moved through the environment (from forest to wetland, from wetland to lake, from lake to sediment, etc.). Cool place. Oh, and the professor's right - you can absolutely taste sulphur dioxide in the air...anyone who's ever hiked around an erupting volcano can tell you that. But it does wonders for your hair, makes it nice and soft!

I’m curious to know if the colour of the liquid would change as it’s forming the droplet. As the water grows to the size of a drop, enough to weigh itself down from the “rain spout”, would the colour of the indicator go from blue to red as the drop grows in size, and what is the colour of the drop, the moment before falling, in comparison to either reservoir. In other words, does the pH of the water drop change as it grows in size, or just while falling? Presumably there’s got to be some sort of relationship between the surface tension of a growing drop, the contaminant particles and the Ph? Or does the water only get contaminated during free-fall?
