Please help me these are the only two I have left.


17. If the solubility of a gas is 5.6 g/L at 505 kPa pressure, what is the solubility of the gas when the pressure is 1010kPa? *




19. Calculate the [H⁺] for the aqueous solution in which [OH⁻] is 1 x10⁻⁹. Is this solution acidic, basic or neutral? Show your work *

<b> The solubility of a gas is directly proportional to the pressure; i.e., the more pressure the higher the solubility. So
5.6 g/L x 1010 kPa/505 kPa = ?</b>

19. Calculate the [H⁺] for the aqueous solution in which [OH⁻] is 1 x10⁻⁹. Is this solution acidic, basic or neutral? Show your work *

<b>(H^+)(OH^-) = Kw = 1E-14
You know OH^- and Kw, solve for H^+.
H^+ > 10^-7 = acid (pH = 0 to 7)
H^+ = 10^-7 = neutral (pH = 7)
H^+ < 10^-7 = basic (pH = 7 to 14)
