Hydroxide and Sulfate IONS

Post by natasha »

You are given a solution that may contain one, both, or none of hydroxide and sulfate ions. How would you test for the presence of these ions?

test for OH- - red litmus paper (if OH- is present, it will turn blue)
test for SO42- - solution of BaCl2 (if SO42- is present, precipitate of BaSO4 will be formed)
