When we add KOH, a strong base, it will increase the pH of the solution. So, the pH will be higher. Solution B: The initial components are H2O and NaOH. NaOH is a strong base, so the initial solution is basic. The term "Nailir" seems to be a typo or a term not Show more…

Fill in the following table, and indicate whether the solution is acidic, basic, or neutral. $$ \begin{array}{ccccc} \hline & \mathrm{pH} & {\left[\mathrm{H}_{3} \mathrm{O}^{+}\right], M} & \mathrm{pOH} & {\left[\mathrm{OH}^{-}\right], M} \\ \hline \text { (a) } & 10.34 & & & \\ \text { (b) } & & & 10.34 & \\ \text { (c) } & & 0.412 & & \\ \text { (d) } & & & & 11.2 \times 10^{-12} \\ \hline \end{array} $$
You have a saturated $\mathrm{Ca}(\mathrm{OH})_{2}$ solution. What would you observe about the solution when these changes are made to separate samples of it: (a) The $\mathrm{pH}$ is increased. (b) Some $6 \mathrm{M} \mathrm{NaOH}$ is added to it. (c) Some $1 \mathrm{M} \mathrm{HCl}$ is added to it. (d) Some $1 \mathrm{M} \mathrm{CaCl}_{2}$ is added to it.
