# Acids and Bases

## Key Questions

A compound with a proton ${\text{H}}^{+}$ that is easily dissociated (removed) into solution. Another way of looking at this is by considering the pH. A pH < 3-4 at ${25}^{\circ} \text{C}$ is considered strongly acidic.
Generally a compound that loses a proton ${\text{H}}^{+}$ in an acid-base reaction which forms a weak (stable) conjugate base in turn is considered a strong acid.
