Question

Write an equation to explain the pH of Na2CO3

Answer 1

sodium carbonate is soluble in water, meaning it will dissolve and dissociate into its ions\[Na_2CO_3(aq) \rightarrow 2Na^{+1}(aq) + CO_3^{-2}(aq)\]the carbonate ion, being negative, will pull away some protons from water molecules, forming some hydroxide ions\[CO_3^{-2}(aq) + H-OH(l) \rightarrow HCO_3^{-1}(aq) + OH^{-1}(aq)\]

Answer 2

since hydroxide ions are being formed, what's the pH of a solution of sodium carbonate?

Answer 3

10.08

Answer 4

even without a number, the pH will be basic because of the hydroxide ions
