A scientist is comparing two lakes. She finds that water samples from Lake X have a pH of 3.50 and water samples from Lake Y have a pH
of 5.50.
Therefore, it can be said that Lake X has a hydronium ion concentration that is
times greater than Lake Y.
Calculate the hydronium ion concentration of a solution with a pH of −1.07.
Consider the following data on some weak acids and weak bases:

formula
HNO₂ 4.5 x 104
acetic acid HCH,CO₂ 1.8x105
acid
nitrous acid
solution
0.1 M HONHYBT
0.1 M KBr
Use this data to rank the following solutions in order of increasing pH. In other words, select a 'l' next to the solution that will have the lowest pH, a '2' next to
the solution that will have the next lowest pH, and so on.
