Describe the process that takes place between the participants in the neutralization reaction between the strong acid nitric acid, HNO3(aq), and the strong base potassium hydroxide, KOH(aq), forming water and potassium nitrate, KNO3(aq). Mention the nature of the particles in the solution before and after the reaction. (a) Because nitric acid is ---Select--- an acid a base a binary covalent compound a binary ionic compound an oxyacid , it reacts with water to form ---Select--- hydrogen atoms hydronium ions hydroxide ions protons...
