A diprotic acid, H2B(MM=126g/moL), is determined to be a hydrate, H2B xH2O. A 10.00-g sample of this hydrate is dissolved in enough water to make 150.0 mL of solution. Twenty-five milliliters of this solution requires 48.5 mL of 0.425 M NaOH to reach the equivalence point. What is x?
A student prepares a weak acid solution by dissolving 0.2400 g HZ to give 100. mL solution. The titration requires 30.0 mL of 0.1025 M NaOH. Calculate the molar mass of the acid. (a) Would the molar mass be too high, too low, or unaffected if the student accidentally used 0.1400 g in the calculation? Explain. ex. too high/too low/unaffected and directly proportional/inversely proportional/ unrelated (b) Would the molar mass be too high, too low, or unaffected if the student accidentally used 20.0 mL instead of 30.0 mL? Explain. ex. too high/too low/unaffected and directly proportional/inversely proportional/ unrelated
For an acid-base titration, the moles of the acid should be equal the moles of the base. 30 mL of aliquot of a 0.23N HCl is placed in an Erlenmeyer flask and 2 drops of phenolphthalein was added. It was titrated and had an intial reading of 15.8 The normality of the solution is found to be 0.52N. (a) How much of the NaOH solution is used for the titration? (b) What is the final reading on the buret?
The next 11 questions are related to the titration of 40.00 mL of a 0.0900 M acetic acid solution with 0.0950 M KOH. Assume that the temperature is 25 oC. What is the pH when 23.00 mL of the KOH solution have been added? What is the pH when 46.00 mL of the KOH solution have been added?

2. Grape juice contains diprotic acid, tartaric acid, which has the molecular formula C4H6O6. If 20.00 mL of grape juice required 36.00 mL of 0.0500 M NaOH for the titration to a pink endpoint, what is the molarity of tartaric acid on the grape juice?
0.015M solution of KMnO4 was titred against 10 mL of FeSO4. The average titre value came out to be 16.6 mL. Given the balanced equation: 2KMnO4 + 8H2SO4 + 10FeSO4 = K2SO4 +2MnSO4 + 5Fe2(SO4)3 + 8H2O. Find the concentration of the FeSO4.
What is the best way to calculate the following titration: 100 ml water and 100 ml of solution with citric acid with pH2 is mixed togeather so the total volume is 200 ml. Then i titrate with NaHCO3 with the following grams. 0.62 gr , 1.82 gr , 2.40 gr What is the pH after each addition of NaHCO3. Please show details, along with the pKa and how it is used as I am very stuck on this and getting it wrong

In order to adjust the AgNO3 solution prepared as 0.1M, 25 ml of the standard NaCl solution with a concentration of 0.1025M is taken and necessary procedures are carried out. Since 24.3 ml AgNO3 solution is used for the titration, what is the concentration of AgNO3 solution?
You are performing an experiment in lab that involves the titration of 25.0 mL of H2SO4 solution. You titrate the acidic solution with 0.8067 M NaOH and the equivalence point is reached by the addition of 17.31 mL of NaOH solution. Using the balanced equation below, calculate the molartity of H2SO4 in the flask. Do NOT include units. 2NaOH(aq) + H2SO4(aq) --> 2H2O(l) + Na2SO4(aq)
-Are ‘equivalence point’ and ‘end point’ the same? If yes, why? Otherwise, differentiate the two. -Aside from repeating the experiment, what can be done to remedy a sample that is ‘over-titrated’. -If the manufacturer claims 4.5% acid content, what does it mean if you calculated 4.67%
