Decomposition of Sodium Bicarbonate (Baking Soda)

[@opmuneer4915]

Thank you! this helped me so much cuz my teacher ain't explaining anything in online school.

[@AnneSchmidt]

Awesome to hear the video was helpful! Best wishes.

@@AnneSchmidt is the reaction the same with potassium bicarbonate

[@AnneSchmidt]

It is more complicated with K2CO3. chemistry.stackexchange.com/questions/121515/thermal-decomposition-of-k2co3

[@THTKIDTONY]

@@AnneSchmidtthanks but is there a vid of it being heated i need to make and observation for a lab....and I'm only seeing the baking soda ones

[@AnneSchmidt]

@@THTKIDTONY one possible answer is the same as the baking soda just switch the Na for K and since they are both 1+ ions that could be one answer. It also is a white solid.

I'm watching this for my Laboratory Alchemy course. Very well done. Dennis Hauck says this experiment compares to the human body's metabolism, oxygen is taken in during inhalation to support combustion, carbon dioxide is removed during exhalation. Or in a spiritual sense the release of water vapor represents the ego or spiritual attachments to the current situation. I'm 38 wish I paid attention in high school.

Glad the video was helpful !

2NaHCO3(Baking Soda) ---Heat--> Na2CO3(Washing Soda) + H2O + CO2

Sure is!

I’m doing this right now lol , I have to write a CER for it

[@matthewlarios.]

it was pretty fun though like idk i like chemistry

[@matthewe3813]

Explained much better than Mr L....

Hey so I was wondering when I would use this information outside of school and when I grow up. :|

[@AnneSchmidt]

Gaining the skills of attention to detail, taking observations, making predictions and following procedures is something every adult uses in their jobs.

[@-thesignpainter9486]

Chances are you won't actually use the information, but learning this (and learning anything) can help build skills and improve ways of thinking

[@degreatal]

hey I came here for cooking purpose, chemistry isn't just for chemists. you'll never know which knowledge would be useful in your life ahead or even safe your life! it doesn't hurt to learn things!

[@degreatal]

I hope you read my comment, please don't complain about learning something! we have no guarantee that the knowledge we have will be useful in real life ... BUT the character that we build while learning something positive (definitely not learning bad things) is also what matters most!

[@lukasgoza4493]

You might find it a fun hobby later in life and wish you knew more about it! I didn't pay attention in school and now here I am learning what I missed.

[@msittig]

Could you briefly explain the point of the "pretzeling" of the gas hose?

[@AnneSchmidt]

As a teacher who has 150 students come through lab in a day. It’s a quick easy effective way to know the gas jet is not left on. Leaving a burner hose still attached leaves room for mistakes turning off the gas. It also allows for the burner to lay flat and take up less space to clean up the area.

[@msittig]

@@AnneSchmidt Thank you!!

[@jillianconnolly2483]

Are the masses correct in this lab? I'm using it as a sub for my virtual students and the numbers seem to be suggesting sodium oxide as the product, which is not correct.

[@AnneSchmidt]

Yes they are and prove the correct solid with very low error.

[@jillianconnolly2483]

Anne Schmidt Thank you. I must have calculated incorrectly. Thank you for the great video! It saved me time since I have inperson and virtual students. I appreciate you!

Is there a way to see the lab report of this?

[@AnneSchmidt]

Sure is! Open the link below 👇🏻 and it will force a copy of the google doc of the lab sheet that goes with this lab video. docs.google.com/document/d/1MOV5P6f1yuJQaD4CYz2rOVTUNO3i4dhHnYUn6KioB1c/copy

Why we heated the sodium bicarbonate?

[@AnneSchmidt]

Without the heat you won't cause the sodium bicarbonate to decompose into the products.

[@lad3394]

this video is valid, can we get a chug jug check?

[@pontocinza]

I use baking soda to remove moisture from books and, as far as I see, it's possible to dry a certain amount of baking soda in a (not too hot) oven without decomposing it. This way I could reuse the baking soda again and again. Do you see any flaw in this reasoning?

[@AnneSchmidt]

That's a great idea!

[@pontocinza]

@@AnneSchmidt Thanks for the feedback, Anne!

[@cococustomz9214]

why is it important to do a second heating?

[@soumadipdasviib3655]

The gas evolved is water vapour (9h2O)

[@virality365]

Anhydrous sodium hydroxide?

[@hehehehe5729]

may i know is there any physical changes after heating it up?

[@avinashanoop8490]

we can see a slight diffrence between NaHCO3 and Na2CO3 if we look very closely.

[@wilsonjacinto3109]

What is the remaining white crystal?

[@AnneSchmidt]

Sodium carbonate.

[@mbhargavi9702]

At what temperature will it decomposed..in water

[@AnneSchmidt]

It doesn’t decompose in water, but it would dissolve in water.

[@drmoezawaung]

Hi. What happens when we heat saturated sodium bicarbonate solution in water? Instead of powder form.

[@avinashanoop8490]

the water will boil off and the remaing sodium bicarbonate will turn into Na2CO3

[@MagixVFX]

The water will evaporate which leave the sodium bicarbonate to solidify and decompose into sodium carbonate

[@knowledgepedia8591]

Which chemical can changes blue to white colour ?

[@dennynguyen9961]

copper sulphate pentahydrate --heat-> copper sulphate + H2O (gas)

What is the white salt compound? Tell me a third product name?

[@AnneSchmidt]

My students have to find out if it is sodium hydroxide, sodium oxide or sodium carbonate using the mass data and stoichiometry.

[@opmuneer4915]

it's sodium carbonate and the balanced equation is 2 NaHCO3 → Na2CO3 + H2O + CO2

[@rnk5537]

OP MUNEER yes

[@fuugawa741]

@@AnneSchmidt how to calculate the mass data? For example, I got 2.00g of NaHCO3, how much of NaOH or Na2O or Na2CO3 in gram will I be expecting before I can compare the final gram left from the experiment.
