The precipitate from the hydrochloric acid and silver nitrate solution went through chemical change because the precipitate cannot change back to the original liquid form. Question 16. Hydrochloric Acid (HCL), Isopropyl Alcohol "Do not do demos unless you are an experienced chemist!" For each pair of solutions, we note the ions present in the reactants, and write the cation-anion combinations if any of them are insoluble or soluble. Rather than losing electrons, the silver ions in the nitrate solution gain electrons as they undergo reduction. They call this a precipitate. Write a balanced chemical equation for each of the following & determine the type of each reaction.
