A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly
