A solution is considered acidic if it has more hydrogen ions (H) than hydroxide ions (OH), meaning the concentration of H is higher, which gives it a pH less than 7. A basic (or alkaline) solution has more OH ions than H ions, resulting in a higher concentration of OH and a pH greater than 7. A neutral solution has equal amounts of H and OH ions, which gives it a pH of exactly 7, like pure water. So, the acidity or basicity of a solution depends on the balance of these ions, affecting its pH level. Give me a reasoning why and address real world applications of understanding acids and bases/ Include in the explanation the substance milk or egg whites. And if there are any dangers with those substances why or why not? And this should be tied into the ion concentrations in the solutions
