Question

THE CONCENTRATION OF HYDROGEN ION IN TWO SOLUTION ARE 1X10-14mol dm3 and 5x10-9 mol dm3.what is the ph of each solution
What is your problem in knowing what to do. We help but we don't work all of your problems.
pH = -log(H^+). Plug in H^+ and solve.
By the way, all caps makes it hard to read.
