do electrolysis of metal and NaCl, the sample will not be the most pure, but you can recrystalize it.

ionic equation (using copper as the metal)
2Na+ + 2Cl- + Cu2+ + 2H+ + 2OH --> CuCl + NaOH + H2

Or just electrolysis of NaCl alone, the hydroxide ions from water will bond with the Na+ ions.

Wow- so much work/expense just to make sodium hydroxide. Amazing. Its the bleach of the chemical industry.

(also, CaSO4- another name is plaster of paris, I believe...)
