Potassium Carbonate can work as a base by creating potassium hydroxide by the break down of carbonate into carbon dioxide and water. However, you may visit "Cookie Settings" to provide a controlled consent. Yes! ( Note : HI is a strong acid; HF is a weak acid) Solution: (F , Cl, Br, I F is the smallest and I is the largest in size) The radius of I is larger than the radius of F. This is why the H-I bond is weaker than the H-F bond, HI is easier to break than HF, and the Ka for HI is greater. Considering that CO3, or carbonic ACID, this substance would be Explain why the ionization constant, Ka, for HI is larger than the ionization constant for HF. $\ce{HCO_3^-}\ (K_{a(HCO_3^-)}={5\times10^{-11}})$, so this solution will alkaline.
