![]() ![]() ![]() Precipitation reactions serve important functions. The solid that forms via a precipitation reaction is called the precipitate. For example, When Sodium Sulphate solution is mixed with Barium Chloride solution It forms Barium Sulphate and Sodium Chloride solution. A soluble compound is one that will dissolve in water. (You cannot swap both you would end up with the same substances you started with.) Either perspective should allow you to predict the proper products, as long as you pair a cation with an anion and not a cation with a cation or an anion with an anion. To precipitate is to form an insoluble compound, either by decreasing the solubility of a compound or by reacting two salt solutions. A reaction in which any insoluble solid precipitate is formed is called Precipitation Reaction. One of the ways a recipitate can be formed is when two soluble compounds interact. Both compounds are white solids that can be dissolved in water to make clear, colorless solutions. One example is the reaction between lead (II) nitrate and potassium iodide. ![]() Chemistry is a field of science that deals with established laws. A precipitation reaction is when two aqueous ionic compounds form a new ionic compound that is not soluble in water. There are two equivalent ways of considering a double-replacement equation: either the cations are swapped, or the anions are swapped. Decantation is a process to separate mixtures by removing a liquid layer that is free of a precipitate, or the solids deposited from a solution. d) Precipitate Terms: In the field of science, there are terms that we must be familiar with to understand the field easier. ![]()
