What is Ka for Benzoic Acid? Ka, also known as the acid ionization constant, is a measurement of how strong an acid is. The higher the number, the stronger the acid. When you are looking at K values for acids in solution with water (H2O), it tells you how much H+ ions will be present and how many moles of hydronium (OH-) ions there will be per mole of benzoic acid (c6h5cooh). A solution of benzoic acid (c6h5cooh) that has a ph value 2.45 has a K value equal to 1.0 x 10^-4, meaning that there will only be one H+ ion per OH- ion. This is considered a weak acid. Ka for Benzoic Acid: Ka, also known as the acid ionization constant, is a measurement of how strong an acid is. The higher the number, the stronger the acid. When you are looking at K values for acids in solution with water (H20), it tells you how much H+ ions will be present and how many moles of hydronium (OH-) ions there will be per mole of benzoic acid (c60h50cooh). A solution of benzoic acid that has a ph value 0f 0f 0625 has a K value equal to -0x1013250014073478
