What are metal oxides in nature?
The metal oxides formed of alkaline metal have the formula MO, where M2+ is the metal cation and O2− is the oxide anion. ... Thus the nature of metal oxides is basic rather than acidic or neutral. Note: Nonmetals or metalloids can give oxides which are acidic in nature. They react with water giving an acidic solution.
Which metal hydroxide is least basic?
Which of the following metal hydroxide is the least basic ? Solution : As the ionization enthalpy increases from Mg→Ba , the M-O bond becomes weaker and weaker down the group and hence basicity increases down the group . Thus , Mg(OH)2 is least basic .
