Here is the answers to [[2021 Review HW for Acid Base Test without Weak Acidbase and Buffer]].<br> <br> 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) Acid taste sour and react with <nowiki>HCl</nowiki> with metals (not copper) to from H<sub>2</sub> gas. Bases taste bitter and are slippery to the touch.<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> 5)Strong acid ionize 100% whereas weak acids do not. <br> <br> 6) Yes there is always be a [H<sup>1+</sup>] in solution.<br> <br> 7) Arrhenius, <nowiki>Bronsted-Lowry</nowiki>, Lewis<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> 4) 2.74 L <br> <br> 5) 0.507M<br> <br>
