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.
true
No , this is false.
true false
True. Veins minerals are deposited from solutions like water that flow through cracks in rocks, carrying dissolved minerals which crystallize and form veins as the solution evaporates or cools.
false
A homogeneous system is part of a system with uniform composition and properties, where the components are evenly distributed and indistinguishable at a macroscopic level. Examples include a well-mixed solution or a single-phase alloy.
False. Homogeneous materials have uniform composition and properties throughout, meaning that they do not contain visibly different materials.
True.
Yes, solutions are homogeneous mixtures where all components are uniformly distributed at a molecular level. This results in a uniform composition and properties throughout the solution.
