This means it can easily ionise substances, many compounds, whether ionic, polar or covalent will dissolve in it, therefore more reactions take place while in solution with water. Often in organisms substances must be in solution and water is the solvent. Plants can only obtain mineral salts in solution and human digestion will only dissolve soluble foods, meaning large starch molecules must be broken down into soluble sugars. ... The aqueous and vitreous humours of the eye help maintain its shape too. ... Life originally evolved in an aqueous habitat and still provides an ideal habitat for a ...

1.Outline the characteristics of a system in a state of equilibrium. Many chemical reactions are reversible and never go to completion. Equilibrium can be approached from both directions. For a system in equilibrium the rate of the forward reaction equals the rate of the reverse reaction and the con...
