The pka values of HF, HCI, HBr and HI are 3.2, -7.0, -9.5 and -10.0, respectively. HF is the strongest acid because it etches glass. HF is the weakest acid because it has the strongest covalent bond. HF is a weak acid, because the electron affinity of fluorine is greater than that of the other halogens. HF is a weak acid because F has the most exothermic hydration. HF is the strongest acid because it forms the strongest hydrogen bonds.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
