Potassium carbonate and nitric acid

Answer 1

2K + 2HNO3 ------------> 2KNO3 + H2

Answer 2

Gives potassium nitrate, carbon dioxide and water. Also gives a great deal of heat and a great deal of froth (the carbon dioxide). Making this potentially dangerous as you could very easily get a frothy faceful of hot nitric acid if you don't know what you are doing. Also pointless, as you can buy all of the products very easily and cheaply without running the risk of putting yourself in hospital.

Answer 3

K2CO3 + 2HNO3 --> 2KNO3 (potassium nitrate) + H2O + CO2

Answer 4

in words:

potassium carbonate + sulphuric acid = potassium sulphate + water + carbon dioxide

the balanced chemical equation is:

K2CO3 + H2SO4 = K2SO4 H2O + CO2

Answer 5

H2SO4(aq) + KNO2(aq) = 2HNO2(aq) + K2SO4(aq)

Answer 6

When potassium carbonate reacts with nitric acid, potassium nitrate, water, and carbon dioxide are formed. The balanced chemical equation for this reaction is: K2CO3 + 2HNO3 → 2KNO3 + H2O + CO2.
