15.
Greg the younger building engineer at Verona uses a dangerous biocide that kills the slime in the G-Wing AC units at Verona HS. If his biocide liquid has a pH of 11.1, what is the [H+] in that liquid (in units of moles H+ / liter of solution )?

19.
If a beaker contains 0.00393 moles of H+ ions, in 330 mL of water, a.
What is the [H+]? b.
what is the pH?
20.
If a beaker contains 8.99x10
17 H+ ions, in 0.190 liters of water, a.

21.
If a solution is made by adding 3.44 grams of HNO
3
to 19.5 liters of water… a.
What is the molarity of HNO

? b.
Because every molecule of HNO
3
added to water forms one ion of H+, the molarity of HNO3 will be the same as the molarity of
[H+] in that mixture. Therefore, what is the [H+] of the HNO

mixture you made in the previous problem ? _________ c.
Find the pH of this HNO
3
mixture.
