WitrynaTo tell if K2O (Potassium oxide) forms an acidic, basic (alkaline), or neutral solution we need to recognize the K2O is a metal oxide in Group Two on the Per... Witryna12 lip 2024 · However, the conjugate base of the weak acid is a weak base and ionizes slightly in water. This increases the amount of hydroxide ion in the solution produced in the reaction and renders it slightly basic. A weak acid plus a weak base can yield either an acidic, basic, or neutral solution. This is the most complex of the four types of …

Is K2So4 an acidic salt? - Meritnation
WitrynaWell, I don't know where Wikipedia gets that number, but the pKa of HSO₄ - is 1.99, which means the pKb of SO₄ 2- would be 12.01, making it a weak base. Also, if the pKa is close to 7, then the solution is neutral because of that (despite the fact that that claim makes it a stronger base than the previous pKb of 12.01). Not because: Witryna16 kwi 2024 · ( 3 point) For each of the following salts, identify the ion that will influence the pH of its aqueous solution (if any) and classify the solution as acidic, basic or … WitrynaChemistry questions and answers.
