8. A student conducts an acid-base titration to investigate the change in pH during a reaction between hydrochloric acid and ammonia solution. a. Name a piece of equipment that could be used to provide an accurate measurement of pH during the titration and explain how it would be calibrated. The student transfers 50cm3 of 1.0moldm3 ammonia solution acid into a beaker. During the titration the student adds 50cm3 1.00moldm³ hydrochloric acid from a burette into the beaker and records the pH throughout. b. Sketch the pH curve produced during this titration.
25.0-mL samples "A" and "B" (both containing HCl) were titrated with 0.100 M NaOH. When titrating sample "A", it took 23.8 mL of titrant to reach the endpoint. When titrating sample "B", it also took 23.8 mL of titrant to reach the endpoint. Which of the following is correct? a. Sample A has a higher concentration of HCl b. Sample B has a higher concentration of HCl c. Sample A has the same concentration as Sample B d. We are unable to deduce the concentration of either sample.

The following refers to a titration lab: Would using a wet beaker to measure out the standardized sodium hydroxide solution cause your calculated hydrochloric acid concentration to be smaller than the actual concentration, larger than the actual concentration, or have no effect? Explain your reasoning Would using a wet Erlenmeyer flask to hold the hydrochloric acid analyte cause your calculated hydrochloric acid concentration to be smaller than the actual concentration, larger than the actual concentration, or have no effect? Explain your reasoning.
7. A 10.00-g sample of the ionic compound NaA, where A is the anion of a weak acid, was dissolved in enough water to make 100.0 mL of solution and was then titrated with 0.100 M HCl. After 500.0 mL HCl was added, the pH was 5.00. The experimenter found that 1.00 L of 0.100 M HCl was required to reach the stoichiometric point of the titration. a. What is the molar mass of NaA? b. Calculate the pH of the solution at the stoichiometric point of titration.
Human saliva contains enzymes that start the process of digestion. Human saliva typically has a hydroxide ion concentration of 1.2 x 10-8 mol/L. Determine the pOH of saliva. Do not show your work. Record only your final answer with the correct number of significant digits. Remember, pOH does not have units! Human blood is slightly basic. Calculate the hydroxide ion concentration in a sample of blood with a pOH of 6.55 You MUST show your work. Record your answer in scientific notation with the proper number of significant digits and proper units.
