how to make kcl crystal

It can be generated by two routes that are of instructive but not practical value: One way is to treat potassium hydroxide (KOH) with hydrochloric acid:

    KOH + HCl ? KCl + H2O

This conversion is an acid-base neutralization reaction. The resulting salt can then be purified by recrystallization. Another method would be to allow potassium to burn in the presence of chlorine gas, also a very exothermic reaction:

    2 K + Cl2 ? 2 KCl
