Making a salt

To make a soluble salt from an acid and an insoluble reactant:

Add some dilute hydrochloric acid to a beaker.

Add powdered insoluble reactant to some acid in a beaker, one spatula at a time, stirring to mix. The mixture will effervesce. Continue adding powder until some unreacted powder is left over - it is in excess.

Filter the mixture in the beaker to remove the excess powder.

Allow the water in the solution to evaporate (by heating and/or leaving for a few days) to obtain pure dry crystals of the salt.
