Unformatted text preview: 9.) Indicate, if the following substances are polar or non-polar: Ethanol Ammonia Hexane Tetrachlormethan Water 10.) Explain why the boiling point of water so much higher than the boiling point of ethan, even if the latter one is a larger molecule? 11.) Formulate the ion product constant of water. Does the dissociated grade of water depend on the temperature? 12.) Calculate the H + and OH-ion concentration in [mol/l] of a solution at pH 0 and pH 14. 13.) KOH is a strong base. Calculate the pH of a solution, where 0.005 mol KOH where dissolved in 500 ml water under the assumption that the KOH is completely dissociated in water. 14.) Give an example of a buffer and explain the function of a buffer. 2...
