Question

Put the following acids in order of their INCREASING acid strength: HCl, HS, HBr, H2Se.

Answer

Acid strength increases from left to right across a period and increases going down a group.

Compare your answer with the correct one above

Question

Put the following acids in order of their INCREASING acid strength: HI, HCl, HBr, HF.

Answer

Larger halogen size leads to greater acidity because of weaker H-X interactions.

Compare your answer with the correct one above

Question

Put the following acids in order of their DECREASING acid strength: HOCl, HO2Cl, HO3Cl, HO4Cl.

Answer

For an oxyacid, the acid strength increases as the number of oxygens increase.
