In the graphic, the first reaction shows citric acid producing hydrogen ions, therefore it is an acid. Bronsted-Lowery Definition (1923) - The definition of acids and bases involving hydrogen and hydroxide ions, respectively is much too limiting. A broader definition was proposed by Bronsted and Lowry in 1923. The main effect of the definition is to increase the number of substances that act as bases.
Although the solubility of a solid generally increases with increasing temperature, there is no simple relationship between the structure of a substance and the temperature dependence of its solubility. Many compounds (such as glucose and CH3CO2Na) exhibit a dramatic increase in solubility with increasing temperature.
Solubility is the ability of a solute to dissolve in a given solvent. One way we can describe solubility is by the solute concentration when the solution has become saturated. At this point, adding more solute to the solution won't increase the concentration.This is what has happened to our kool aid.Next is the definition of the rate of solution.lso a solute can be a liquid, a solid, or a gas; although the solute is usually a solid. The factor that most influences the rate of solution is the amount of solute already dissolved in the solution.
