Is this Na2CO3 monohydrate

[AHW214]

@megamarko94

I assume it's not, because even though the water vapor produced could react with the Na2CO3 to form a hydrate, the heat would turn it to anhydrous Na2CO3.

This seemed a bit complicated, especially with the optional items, but you did a very good job in identifying everything and explaining the steps. :) ~ Somewhat related, do you have a microscope and have you done any experiments with or studies of various kinds of crystals?

@maintoc

Technically speaking all you need is a burner, a test tube and holder, and baking soda.

Good job proving your results, keep it up

@hkparker

Thanks!

Good and simple description!

Phenol red indicator will change color with CO2.

Carbon dioxide, when dissolved in water, indeed does form carbonic acid, H2CO3. However, this is unstable and the CO2 is released only a few seconds after being dissolved - also, this acid is VERY weak, that is it only ionises to a small degree in water (releases few H+ ions to contribute towards the hydronium ion total count). So, perhaps the acid WAS present, just that your pH indicator wasn't sensitive enough to detect the brief acidity. Good video by the way!!

@pinkytm1 thank you for the unnecessary explanation I said Ive not heard it be referred in that manner alot "ALOT" being the word...

[pinkytm1]

@c0ldelement Their two different chemicals.

NaHCO3(s) ---heat--> Na2CO3(s) + CO2(g) +H2O (g)

Oh maybe you meant to say you never heard sodium bicarbonate referred to as sodium hydrogen carbonate. They are the same thing.

@AHW214 no biggie Ive just never heard Sodium Carbonate refer to alot as Sodium Hydrogen carbonate... but still nice video

@AHW214 Sorry to hear you don't have a microscope. There's so many cool things to examine with them. ~ Yes, rock candy counts as crystals. That's what it is; crystals of sugar grown from a super-saturated solution. They'll grow on thread or string, or even wooden skewers. Food coloring added into the super-saturated sugar solution will result in colored crystals.
