The hydrogen ion concentration of the lake would be greater (104 M)
The OH concentration of the lake would be greater than the lake.
The lake has a concentration of hydrogen ions three times that of the pure water.
There is acid present in the lake.
There is not any acid present in the lake because the pH is less than that of water.
The lake has a high concentration of salt and may be near an ocean.
