true

For oxoacids, the more electronegative the central atom, the more acidic the compound.

true

true

Hydrochloric acid is a strong acid.

true

If a compound behaves as a Bronsted-Lowry acid in a reaction, it necessarily is behaving as a Lewis acid.

true

In an acid-base reaction, the side with the weaker acid will always be at higher concentration at equilibrium.

true

In some reactions water behaves like a base, in other reactions water behaves like an acid.

true
