True. The concentration of hydrogen ions in a solution directly determines the pH of the solution. A lower concentration of hydrogen ions results in a higher pH, while a higher concentration of hydrogen ions results in a lower pH.
A suspension is a heterogeneous mixture because it doesn't have uniform composition throughout. True for A+
False. Liquid water in air forms a mixture, not a solution. A solution is a homogeneous mixture where one substance dissolves completely in another. In the case of water in air, the water droplets are dispersed throughout the air, but they do not dissolve in it.
A substance that forms hydroxide ions in a water solutoin is a base -- TRUE -- apex:)
False. In equilibrium, the rates of the forward and reverse reactions are equal, but the molecules are still in constant motion due to thermal energy.
