Which of

Question

I) HCl
II) HF
III) LiOH
IV) HClO2
V) HNO3
are strong acids or strong bases in water?

Answer 1

i no the first one and last one are strong but i don't know about the others

Answer 2

I and IV are strong acids. HF is the most common weak acid, and this has to do with electronegativity of F. LiOH is a strong base, I think. And HCLO2 is a weak acid; O's have to outnumber the H's by two or more.

Answer 3

Devron made a typo. I and V are strong acids (HClO2 is indeed weak).

Answer 4

The answer is the strongest acids and bases in water are HCl, LiOH, and HNO3 (I, III, and V).
