Common acids used in everyday life:

sodium bicarbonate (NaHCO3), which is baking soda. You can convert this into sodium carbonate easily. If you heat baking soda at 200C for about an hour, the baking soda will decompose into washing soda, giving off CO2 and water in the process via 2NaHCO3 . Na2CO3 + CO2 + H2O. Let the washing soda cool to room temperature before using. ................
