What is the pH of Na2CO3?

Answer: When calculating the pH of an aqueous solution, the first step is to count the quantity of free H+ ions dispersed throughout the solution. Because Na₂CO₃ is both a salt and a solid, it does not possess its unique pH value.

When dissolved in liquid water, Na₂CO₃ is a salt that, when taken up, will raise the pH (lower the quantity of free H+ ions that have been dissolved in the water). This is because of the salt’s relatively powerful base CO3 2-.

As a result, we are able to conclude that Na₂CO₃ has a pH of 11.
