Question 79065: The ph of a slution ranges from 0 to 14. An acid has a ph less than 7. Pure water is neutural and has a ph of 7. The ph of the solution is given by PH =
-logx Were x represents the conncentration of the hydrogen it has in the solution in moles per liter. Find the hydrogen on concentration if the Ph=3.

PH+=+-log%28x%29
Find x if PH = 3.
3+=+-log%28x%29 Multiply both sides by -1.
-3+=+log%28x%29 Rewrite in exponential form: IfLog%5Bb%5D%28x%29+=+y then y%5Eb+=+x, so...
10%5E%28-3%29+=+x or
x+=+0.001
Answer:
The hydrogen concentration would be 0.001 moles per litre.
