Which substances are acids? check all that apply
lioh *hbr *ch3cooh nacl *h3po4 mg(oh)2
* are the correct answers, just took test

The substance  which is are  acids  are HBr , CH3COOH   and H3PO4

      Explanation

An acid is substance  that releases hydrogen  ions ( H+)  when it dissolve  in  water.

  HBr  , CH3COOH  and  H3PO4  is  an  acid  because  they dissolve in water to  release hydrogen  ions(H+)

for  example    CH3COOH(aq)  →  CH3COO- (aq)  + H+(aq)

                        HBr (aq)→  H+ (aq)  +Br- (aq)

                          H3PO4(aq) →   H+(aq)  +H2PO4-(aq)

HMnO4 and HF

i just got it right sooo yeahh

just took the test

Explanation
