Answer: metal and carbonate
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions [tex](OH^-)[/tex] when dissolved in water and an acid is defined as a substance which donates hydrogen ions [tex](H^+)[/tex] in water.
An acid is represented as :
[tex]HX\rightarrow H^++X^-[/tex]
1. When metal is treated with an acid such as [tex]HCl[/tex], if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.
[tex]M+xHCl(aq)\rightarrow MCl_x(aq)+xH_2(g)[/tex]
2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.
[tex]MCO_3(aq)+xHCl(aq)\rightarrow MCl_x(aq)+xH_2O(l)+CO_2(g)[/tex]
