When HCL is added to a sample of dry potassium carbonate, it fizzes and bubbles up. This is due to the fact that it has a high pH

I did this science practical at school i added half a teaspoon of sodium carbonate to 20 ml of vinegar. It fizzed up then after about ten seconds went down.
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
No reaction would Occur. => No product is formed
no reaction/no change
K+1 CO3-2 ------> these are the ions and their charges K+1 K+1 CO3-2 ------> the charges have to add up to zero, so one positive K atom is added to cancel out the -2 negative CO3 ion K2CO3 ------> simplify Name: Potassium carbonate
2hcl- + k2co3====>2h2co3+2kcl
Chemical
Fluorides of sodium and potassium
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
Potassium is an element--the purest form of any substance. Technically the formula is just K as that is the elemental symbol. There are innumerable different compounds that include potassium in their formula.
You think probable to calcium carbonate.
The color of formaldehyde liquid depends on what other chemicals are added to it. For example, when potassium carbonate is added the solution acquires a violet-blue color.
iodine and chloride ions
The chemical and physical properties are changed.
This element is iodine - added as potassium iodide or potassium iodate.
