Answer the following question using your data from the lab, [[CP pH Reading with pH indicator paper Lab]].<br> <br> <br> 1a) What was the pH of the Tap water? __________<br> 1b) What was the pH of Hydration Station water? _________<br> 1c) What do you think was the reason the two pH values were not the same?<br> <br> <br> 2a) What was the pH of the 0.10M HCl solution. ______<br> 2b) Is HCl a weak acid or a strong acid, circle your answer.<br> 2c) What was the pH of the 0.10M H<sub>1</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>1</sub> ( <nowiki>HAc</nowiki>, Acetic acid) solution. ______<br> 2d) Is <nowiki>HAc</nowiki> a weak acid or strong acid, circle your answer.<br> 2e) Explain why the pH of the two acid solutions are different even though they both 0.10M solutions (i.e. same concentration of the acids).<br> <br> <br> <br> 3a) What was the pH of the 0.10M <nowiki>NaOH</nowiki> solution. ______<br> 3b) Is HCl a weak base or a strong base, circle your answer.<br> 3c) What was the pH of the 0.10 M NH<sub>4</sub>OH (actually NH<sub>3</sub> in solution, called Ammonia water) solution. _______<br> 3d) Is NH<sub>4</sub>OH a weak base or strong base, circle your answer.<br> 3e) Explain why the pH of the two bases solutions are different even though they both 0.10M solutions (i.e. same concentration of the base).<br> <br> <br> <br> 4a) What is the pH of the Grape <nowiki>Kool-Aid</nowiki> solution. ________<br> 4b) How does this pH compare to the pH of the Tap and Hydration station water?<br> <br> <br> <br>4c) Why do you think they are not the same pH values.<br> <br> <br> 5a) What is the pH of Orange juice? _______<br> 5b) What is the pH of the Diet Coke? __________<br> 5c) From these pH values, what can you say about the amount of H<sup>1+</sup> concentration in each solution? Explain why you think they are different.<br> <br> <br> <br> <br>
