What happens when sodium hydrogen carbonate solution is mixed with water?
When sodium hydrogen carbonate (baking soda) is dissolved in water, it dissociates to form sodium ions, bicarbonate ions, and some carbonate ions. This results in a slightly alkaline solution due to the presence of bicarbonate ions which can act as a buffer. The overall pH of the solution would be around 8.4.
Is sodium carbonate an electrolyte?
Yes, sodium carbonate is an electrolyte. When dissolved in water, it dissociates into sodium ions and carbonate ions, which are free to carry electric charge.
What elements make up calcium hydrogen carbonate?
Calcium hydrogen carbonate is composed of calcium ions (Ca^2+), hydrogen carbonate ions (HCO3^-), and water molecules (H2O). When dissolved in water, calcium hydrogen carbonate dissociates to form these ions.
Is sodium carbonate soluble in aqueous solution?
Yes, sodium carbonate (Na2CO3) is soluble in water. When dissolved in water, it dissociates into sodium ions (Na+) and carbonate ions (CO3^2-).
What does a base produce when dissolved in water?
When bases dissolve in water, they usually form alkaline solution. An alkaline solution has a pH that is more than seven.

When carbonate minerals come into contact with hydrochloric acid?
Fizz. Carbonate mineral are alkaline and these react with the acid to produce a chloride salt and Carbon dioxide gas.
Why is Na2CO3 alkaline in nature?
Because it contains sodium cations, which are strongly basic, and carbonate anions which are weakly acidic. So the basic ions win over acidic ions, making Na2CO3 alkaline(i.e. basic).
Can potassium carbonate dissolved in water conduct electricity?
Yes, potassium carbonate dissolved in water can conduct electricity because it dissociates into ions (K+ and CO3^2-) in solution, allowing for the flow of electric current. This is due to the presence of free ions that can carry the charge.
Can calcium carbonate conduct electricity when dissolved?
Calcium Carbonate is insoluble in water, however calcium carbonate itself is an ionic compound and ionic bonds do conduct electricity.
Is (NH4)2CO3 soluble or insoluble?
All ammonium salts (containing NH4+ ions) are soluble.
Why sodium carbonate being a salt acts as an alkali metal?
It is not an alkali metal, but it is alkaline. The carbonate ion is a weak base; it reacts with water in small amounts to form bicarbonate ions and hydroxide ions.
Is calcium hydrogencarbonate insoluble or soluble in water?
Calcium hydrogen carbonate is soluble in water. It dissociates into calcium ions (Ca²⁺) and bicarbonate ions (HCO₃⁻) when dissolved in water.
