Based on the solubility rules, which of the following will occur when solutions of ZnSO4(aq) and MgCl2(aq) are mixed? A) ZnCl2 will precipitate; Mg2+ and SO42– will be spectator ions. B) MgSO4 will precipitate; Zn2+ and Cl– will be spectator ions. C) No precipitate will form. D) ZnSO4 will precipitate; Mg2+ and Cl– will be spectator ions. E) MgCl2 will precipitate; Zn2+ and SO42– will be spectator ions. I know the correct answer is C (No precipitate will form). Why is that, considering MgSO4 is a solid as a product? I was under the assumption that a solid is considered a precipitate, since I initally thought it was answer B.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
