In aqueous solutions, reactions typically involve substances dissolved in water, where water serves as the solvent. The substances dissolved are called solutes, and they can be ionic or molecular compounds. Here are the common types of reactions that occur in aqueous solutions: 1. Precipitation Reactions These occur when two aqueous solutions are mixed, and an insoluble solid (precipitate) forms. Example: Mixing silver nitrate (AgNO₃) and sodium chloride (NaCl) solutions forms a precipitate of s

Kevin Sir's Arham Academy on Instagram: "When aluminum (Al) reacts with copper(II) sulfate (CuSO4) and hydrochloric acid (HCl), the following reactions occur: Aluminum displaces copper from copper sulfate in a single displacement reaction, producing copper and aluminum sulfate. Aluminum reacts with dilute hydrochloric acid to produce aluminum chloride and hydrogen gas. When concentrated hydrochloric acid is added to a dilute copper sulfate solution, the solution turns yellow-green due to the for
