  Factors affecting Solubility; Solubility of v Solid in Liquid v Gas in Liquid v Liquid in Liquid Solid in Liquid: When Solute   is in solid form and   solvent   is in liquid form and then solid dissolve in the liquid. Factors: o    Nature: If Nature is Same, solubility is good. E. g.- Polar solute in polar solvent. o    Surface Area:   If surface area of the solute is more, solubility increases. o    Temperature: When we dissolve solid into liquid, two reaction occurs à §   Exothermic:   Heat releases for dissolve. §   Endothermic: It absorb heat for dissolve.   Gas in Liquid: When solute is in gas form and solvent is in liquid form. -          Nature does not affect the solubility. Factors: o    Surface area: Directly proportional to solubility. o    Temperature:  ...

 

Terms of pH The 'p' in pH stands for "potenz" meaning "power" in Danish. Since the scale was given by a Danish Chemist Sorensen.  H stands for Hydrogen and is its symbol. Hence H is written in capital letter.
