A solution container was only label 0.005M. When phenolphthalene was added onto the solution, the color of the solution turned pink. After identifying the type of solution,it was later titrated with sodium carbonate. If the solution was sulphuric acid,determine the (a) [H+] , (b) [OH-] , (c) pH
I don't know about this. No concn Na2CO3 given. Also, I don't know of any H2SO4 solution whose pH is 8 or higher (where phenolphthalein turns pink).
