Will the solubility of CaCO3 in water increase or decrease if the pressure of CO2 gas above the saturated solution is increased? Note that CO2 gas reacts with water to produce a weak diprotic acid H2CO3. This acid can undergo the loss of one or two protons to form HCO3- and CO32- ions (these are bicarbonate and carbonate).

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.
