A student determines that 37.2mL of 0.1543 M NaOH is required to titrate 25.0mL HCl. What is the concentration of the acid? The student consistently titrates to a dark pink endpoint. Will the reported value for the concentration of acid be too high, too low, or unaffected by the dark pink endpoint? Another student performs the titration and does not notice the air bubbles trapped in the tip of the buret. How will the reported value for the concentration of...

A student performs the titration of 25.0 mL of HCI with 0.1 M NaOH. If the acid concentration is 0.1 M and 35.0 mL of base are added, the hydroxide concentration and the pH are: [OH-] = 1.67 times 10^-2 M, pH = 12.22 [OH-] = 3.5 M, pH = 13.46 [OH-] = 1.67 times 10^-2 M, pH = 1.78 [OH-] = 2.58 times 10^-3 M, pH = 13.51 the pH at the equivalence point when a 0.20 M weak...

Questions: 1. 495 mg of dried KHP is dissolved in 35 mL of distilled water and titrated with potassium hydroxide (KOH). If it took 22.02 mL of KOH to reach the endpoint, determine the concentration of KOH. Show calculations. If you forgot to dry the above KHP sample and it was later determined to contain 5.00 % water by weight, what would be the actual concentration of the KOH, taking into account the water content? Show calculations. 2. If you...

1. A volume of ___ mL of 0.100 M NaOH(aq) is required to titrate 0.500 g of potassium hydrogen phthalate (often abbreviated KHP) to the endpoint. 2. A 0.5741 g sample of a monoprotic acid was titrated with 0.1008 M NaOH(aq). If 37.89 mL of sodium hydroxide solution were required for the titration, the molar mass of the monoprotic acid is ___ g/mol.
