pH is the negative log of the hydrogen Ion concentration. So there is an inverse relationship between the pH and the hydrogen Ion concentration.

It is because the ph is calculated by taking the -log of the concentration of Hydrogen. For example if the concentration of Hydrogen is 1x10-7 M, the pH would be 7. If you increase the concentration of hydrogen by adding more acid, like making the solution contain 1x10-3 M, the pH would be 3. It continues to follow this pattern and even can go negative.

Convention, adopted to avoid negative numbers.

It's a NEGATIVE logarithm! It's INVERSE.
