Calculate the pH of a solution made by dissolving 0.070 mol of methylamine in water and diluting to 800.0mL. Conceptual Problems 8. The different definitions of acids/bases contradict each other. T F 9. A solution with a low pH has a low concentration of hydronium ions. T F 10. Strong acids are weak electrolytes. T F 11. pH is temperature dependent. T F 12. Nothing can act as both an acid and a base. T F 13. You should determine if you have a strong or weak acid/base before starting the problem. T F 14. Strong acid and base problems cannot be solved with (R)ICE charts. T F 15. Strong acids have low pHs and strong bases have high pHs. T F 16. The value of Kw is 1.00*10 ­14. T F 17. Strong acids and bases are dangerous. T F Page 4 of 4...
