    Ca(OH)2 and Mg(OH)2 are strong BASES.

    There is a list of strong acids and bases, memorize it-- it's short.

    # Perchloric acid HClO4

    # Hydroiodic acid HI

    # Hydrobromic acid HBr

    # Hydrochloric acid HCl

    # Sulfuric acid H2SO4 (Ka1/first dissociation only)

    # Hydronium ion H3O+ or H+. For purposes of simplicity, H3O+ is often replaced in a chemical equation with H+. However, it should be noted that a bare proton simply does not exist in water but instead is bound to one of the lone pairs of electrons on the H2O molecule.

    # Nitric acid HNO3

    * Potassium hydroxide (KOH)

    * Barium hydroxide (Ba(OH)2)

    * Caesium hydroxide (CsOH)

    * Sodium hydroxide (NaOH)

    * Strontium hydroxide (Sr(OH)2)

    * Calcium hydroxide (Ca(OH)2)

    * Lithium hydroxide (LiOH)

    * Rubidium hydroxide (RbOH)

    * Magnesium hydroxide (Mg(OH)2)

    They are not acids, they are fairly strong bases...hydroxide anything in general is a base. It can accepts a proton, in the form of a Hydrogen quite easily.

    since there are OH groups these are actually bases, so they would be week acids
