Part I<br> 1. Hydrosulfuric acid, weak <br> 2. H<sub>2</sub>Se, weak<br> 3. Sulfuric acid, strong<br> 4. H<sub>2</sub>SO<sub>3</sub>, weak<br> 5. Calcium hydroxide, strong<br> 6. H<sub>3</sub>PO<sub>4</sub>, weak<br> 7. NH<sub>3</sub>, weak (base)<br> 8. Carbon dioxide, non-electrolyte<br> 9. Barium chlorite, strong (ionic compound)<br> 10. Nitrous acid, weak<br> <br> Part II<br> 1. All solution are same molarity so difference are strong and weak and how many H<sup>+</sup> ionizes per molecule of acid. HF is weak acid so it has highest pH, and sulfuric acid has 2 H<sup>+</sup> per molecule so it has lowest pH.<br> <br> 2. pH indicator indicates a pH (actually a pH range). The weak acid, that is the indicator, changes colors.<br> <br> 3. 2016-2017 students do not do<bR> <br> 4. pH = -log [H<sup>+</sup>] , pH value and [H<sup>+</sup>] are indirectly proportional. It can be show in the math by the negative sign.<br> <br> <br> Part III<br> <br> 1. pH = 1.988<br> <br> 2. 3.58E-4M<br> <br> 3. pH = 10.73<br> <br>
