in a Precipitation Titration of Cobalt Chloride lab Suppose you did not have any indicator available. How else would you be able to identify the end point of the titration?

Suppose in a titration of a diprotic acid a student needed 31.84 mL of 0.1105 M NaOH to reach the phenolphthalein endpoint. If the mass of the unknown acid was 0.2706 g, calculate the molar mass of the unknown acid in grams per mole. Type answer:

The reason a buffer is able to maintain its pH against the addition of a strong acid or base is...b) Both buffer compounds will neutralize the added strong acid or base.a) Both of the buffer compounds will cause a Le Chatelier’s shift.c) One of the 2 buffer compounds will cause a right Le Chatelier’s shift.d) One of the 2 buffer compounds will cause a left Le Chatelier’s shift.

Which of the following best describes the titrant solution in a titration? O a variable concentration O a known concentration O an unknown concentration O an indicator solution
