we must combine sodium carbonate with which acid to get sodium sulphate?
To determine which acid to combine with sodium carbonate to produce sodium sulfate, we need to consider the chemical equation involved in the reaction.
The general equation for the reaction between a carbonate and an acid is as follows:
Carbonate (CO3^2-) + Acid --> Salt + Water + Carbon Dioxide
In this case, we want to produce sodium sulfate (Na2SO4) as the salt. Therefore, we need an acid that contains the sulfate ion (SO4^2-).
One such acid that meets this requirement is sulfuric acid (H2SO4).
So, by combining sodium carbonate (Na2CO3) with sulfuric acid (H2SO4), the reaction occurs as follows:
Na2CO3 + H2SO4 --> Na2SO4 + H2O + CO2
By balancing the equation, we can see that 1 mole of sodium carbonate reacts with 1 mole of sulfuric acid to produce 1 mole of sodium sulfate, 1 mole of water, and 1 mole of carbon dioxide.
Remember, it is essential to balance the equation to ensure the correct stoichiometry of reactants and products.
