A "strong" acid (or base) is one that dissociates completely in dilute aqueous solution. One which does not is a "weak" acid (or base). An acid with a pKa (or a base with a pKb) lower than about -2 is considered to be a "strong" acid.
Weak acids and bases can still be quite corrosive. HF is a "weak" acid with a pKa of around 3.2 (which corresponds to only about one molecule out of every 38 or so being dissociated), but it's pretty terrible stuff and will dissolve even glass.
HCI (Hydrochloric acid)
1/2 is less than one.
The reaction would shift to balance the change
Ka= [h+][HCO3-]/[H2CO3]
the reaction would shift to favor the side with the most moles of gas
Balance H2 plus N2 equals NH3
3H2 + N2 ----> 2NH3
The equilibrium of the system will be upset.
This is called molality.
