Weak acids are only partially ionized when dissolved in water. This means that the pH is higher (more to neutral) at a given concentration of the acid, than is the case with a [[strong acid]].
Examples are vinegar/acetic acid, citric acid and fumaric acid.

Popol Vuh: Created page with "Strong acids are completely ionized when dissolved in water. Examples: HCl, H2SO4. Opposed to a weak acid."

Strong acids are completely ionized when dissolved in water. Examples: HCl, H2SO4.
Opposed to a [[weak acid]].

Popol Vuh:

A salt in chemistry is a solid at room temperature, made of metal-ions and non-metal-ions1. It can only dissolve in polar solvents like water.
Some salts are pH neutral (eg. NaCl = rock salt used for cooking), some are basic (eg. NaOH) and some are acidic (eg. NaH2PO4).
Some salts are very solvable, some are almost insolvable. The higher the temperature of the solvent, the more of a salt can dissolve.

Not everything that is ionized in water is a salt. HCl (a [[strong acid]]), and vinegar/acetic acid CH3COOH (a [[weak acid]]), form ions as well, but are molecular substances.

1 There are a few exeptions to this rule. NH4+, the ammonium-ion forms salts without a metal-ion (eg. NH4Cl, salmiac salt).
