    The total concentration of ions in a 0.75 M solution of HCl is 1.5 M

    That is; 0.75 M H⁺ and 0.75 M Cl⁻

    Explanation: Concentration or molarity is the number of moles of a compound or an ion contained in one liter of solution. It is measured in moles per liter (M). The concentration of ions making a compound is determined by the ratio of moles of the compound and the constituents ions. For instance, HCl dissociates to give H⁺ and Cl⁻

    HCl (aq) → H⁺ (aq) + Cl⁻ (aq)

    Therefore, since the mole ratio between HCl and the constituent ions H⁺ and Cl⁻ is 1:1, then 0.75 M of HCl dissociates to give 0.75 M H⁺ and 0.75 m Cl⁻ Hence the total concentration of ions in a 0.75 M solution of HCl is 1.5 M (0.75 M H⁺ and 0.75 M Cl⁻)
