Answer #1

Bleach has two ions, cation is Na+ which can be tested by flame test.

Mix small amount of substance with concentrated HCl and heated on a bursen burner on a nichrome wire. Appearence of golden yellow flame confirms presence of Na+ ion.

Anion in bleach is OCl- is tested by addition of I2 to the bleach. OCl- in bleach is in equilibrium with Cl- and OH- in solution and gives Cl2. Addition of iodide to it, forms I2 (purple color) which reacts further to give brown coloration to solution due to I3- formation. This confirms presence of OCl-.
