How can you make Soluble Salts, with an Acid and Insoluble Reactant? [Base]

-First, pick the Correct Acid and Metal/Insoluble Base -Put the Base in the Acid, and it will react to make a Soluble Salt plus Water -When all the Acid has been Neutralised, the Excess Solid will sink to the Bottom of the Flask [Heating up the Flask can help the Reaction] -Finally filter off the Excess Solid to gain a Solution with Salt and Water -Then Heat your Solution gently, to evaporate some of the Water. Then let it cool off and have it Crystallise. Filter the Solid off, and let it Dry [Example can be Copper Oxide to Hydrochloric Acid making Copper Chloride]
