For which of the following solutions must we consider the ionization of water when calculating the pH or pOH?$$\begin{array}{l}{\text { (a) } 3 \times 10^{-8} \mathrm{M} \mathrm{HNO}_{3}} \\ {\text { (b) } 0.10 \mathrm{g} \mathrm{HCl} \text { in } 1.0 \mathrm{L} \text { of solution }} \\ {\text { (c) } 0.00080 \mathrm{g} \mathrm{NaOH} \text { in } 0.50 \mathrm{L} \text { of solution }} \\ {\text { (d) } 1 \times 10^{-7} \mathrm{M} \mathrm{Ca}(\mathrm{OH})_{2}} \\ {\text { (e) } 0.0245 \mathrm{M} \mathrm{KNO}_{3}}\end{array}$$

okay. As the concentration off Jenna Tree is three in 10 days to party ate him so the concentration off hydro new mine produced would be the same. So as the concentration off my drone in irons produced is less than 4.5 to 10 days super minus seven. Hence, the ionization off water should be considered by calculating the pH and sewage. For part B, we have the Moler months that the study's explained for six gram the number off moles off, etc. L equal Baylin toe 36.4606 prom off. It can be calculated as shown, therefore the concentration off, etc. L in one liter of solution is calculated which turned out to this 10.3 a. M as the concentration off etc. Ellis's 0.3 so the concentration off Adonia mine would be the same. Therefore it is greater than 4.5 entertain the super minus seven and the ionization off water should not be considered for anywhere. We have the molar mass. We have the number off moles, the amount off mole which turned out to be two point there under tender super minus Phi. Therefore, the concentration off an A, which in 2.0.5 liter of solution is calculated that is 4.0 into 10 based upon minus five, the concentration off hydroxide ions would be the same as four point. They're going to turn this upon minus five, which is greater than 4.5 into 26 minus seven. Hence, the ionization of water is to be considered for body as the concentration off CEO, which toe is one in to attend the super minus seven. So the concentration off I don't mind produce would be the same as that off it. So as the concentration off, I don't mind. It is less than 4.5 into 20 so common in a seven, the ionization of water should be considered for part e. The concentration off key and No. Three is point 245 them. But the reaction off care no tree with water will result in tow. Neutral solution, as care not really, is electrolyte. Hence, the ionization of water should be considered. While calculating the Ph
