Plot Twist: This wasn’t recommended, I was just looking for this

[@ReubenLL28]

It really seems like you should be more careful about mistakes when you make this type of video. First of all, calcium is much softer than either magnesium or beryllium, not harder. You have the periodic trend backward. Beryllium (mohs) hardness: 5.5 Magnesium hardness: 2.5 Calcium hardness: 1.75 Strontium hardness: 1.5 Barium hardness: 1.25 Also, calcium is not normally stored in air, but rather in mineral oil to prevent its reaction with oxygen, nitrogen and moisture. If you need to keep calcium metal for any extended length of time, mineral oil is a must.

[@harshvardhansinghkushwah8678]

funfact : the calcium floats on water as evlove hydrogen gas stick on the surface of metal and also calcium reacts with cold water

[@malugaoaprilrose3946]

What happens when you cover the flask with water and calcium with a watch glass (avoid exposing on air)? Will it still react the same?

[@talibannejad9771]

Phenolphthalein*, you mean.

[@atharvtambe14]

It's Ca(OH)2 so would it react with CO2 to form Carbonate? If we just pass CO2 in that flask?

[@acerslatestvideos7031]

1:12 Now it makes sense why milk and bone are white.

[@swapnanilmandal2250]

Umm.... one question.... in school we were taught that calcium burns in water with a flickering brick red flame? Why was there no flame?

[@JIYASINGH14]

It doesn't burn in water because the reaction is not that exothermic like Na, K etc.

[@VishuSplendid01]

Does calcium will float also?

[@limmuquan4796]

According to wikipedia, the density of calcium metal at room temperature is 1.55g/cm3 so it shouldn't float on water
