A. Hydrochloric Acid Solution and pH 1. Write the balanced chemical reaction for the dissociation of the hydrochloric acid. 2. Refer to the procedure for A to determine the concentrations of the solutions of hydrochloric acid. Remember to use MiV1-MV. Show work for trial 1. 3. Calculate the theoretical pH of each hydrochloric acid solution. Recall that hydrochloric acid is a strong acid, suggesting complete dissociation, so that the equation pH log (HO) can be used (equation 3). Show work...

Strong Acids and [H'] (and pH) The pH of a strong acid is the concentration of the strong acid. 1.OM HCI makes 1.OM H. Except H2SO4. Its pH is a little lower than that because: H2SO4(aq) H+ (aq) + HS07 (aq) Strong acids generally have K.>>1. We assume K = . The HSO, is a weak acid: HSO2 (aq) + H+ (aq) + S0 - Ka = 1.2 * 10-2 Weak Acids and [H+] (and pH) These are weak electrolytes....

The Na,Co, solution described above was used to analyse a hydrochloric acid solution of unknown concentration. It was found that 24.30 mL of the Na,Co, solution was required to neutralise a 20.00 mL sample of the hydrochloric acid solution. 4. Using your answer to part 3 above, calculate the amount of Na,Co, present in 24.30 mL of the Na,Co, solution. (2 marks) 5. Using your answer to part 2 above, deduce the amount of HCl that was present in the...

4 June 2019 CHEM 177-Su19 Chapter 4 APP-1 4. Hydrochloric acid (HCI) is generally sold as an 11.65 M solution. When doing titration experiments, many will use an HCl concentration of 1.00 M HCl. If you wanted to make 150 mL of 1.00 M HCI, how many mL of the stock HCl solution would you need? 5. A 4.00 L stock solution of H3PO4 of unknown concentration was mixed with 4.00 L of pure water. The concentration of the new...
