The ionization of water is an endothermic process. a.)What happens to the value of Kw as water is heated? explain.. b.) What happens to the pH of pure water as the temperature increases? and c.)as the temperature of pure water rises, will the water become mor acidic, more basic or remain neutral... all i know is that if its endothermic A + B + Heat = C + D and if we increase the heat, the system shifts to the left..so what happens to the Kw?
