A student tested some solutions with universal indicator paper and wrote down their pH values are: 1,5,7 and 13 but the forgot to write the names of the solutions. Can you help him by matchicng the pHs to the correct solution:

A cell consists of two hydrogen electrodes. The negative electrode is in contact with a solution having pH=6. the positive electrode is in contact with a solution of pH=x. calculate the value of x if the e.m.f of the cell is found to be 0.118V at 298K
