Determine whether the following hydroxide ion concentrations ([OH−]) correspond to acidic, basic, or neutral solutions by estimating their corresponding hydronium ion concentrations ([H3O+] using the ion product constant of water (Kw). It may help to keep the following equation in mind as you work Kw = [H3O+][OH−] = [1×10−7 M][1×10−7 M] = 1×10−14 M. 1. [OH-] = 4 x 10^-12 M 2. [OH-] = 7 x 10^-9 M 3. [OH-] = 7 x 10^-4 M 4. [OH-] = 2 x...

1. The following table lists the ion composition of water. What are the mg/L concentrations of each? Does this water have charge balance? If no, then some ion is missing. Would it be a cation or an anion? From these values compute the TDS in mg/L and the hardness in mg/L as CaCO3. Are these values low, normal, or high? Is any other ion out of the desired range?
