Can someone please help me with this questions? EXPERIMENT 6 DATA CALCULATIONS Determine the molar mass of Monoprotic Acid used in this experiment from the following data obtained during the course of this experiment: a) 40 ml of pre-prepared 3.0 g/L of an unknown monoprotic acid in a 100 mL beaker for titration with sodium hydroxide using Ph meter. b)Molarity of sodium hydroxide Mb=0.0768 moles/L determined by titration with known strength of khp. c)Volume of sodium hydroxide to equivalence point=23.5mL...
5. The Ka and Molar Mass of a Monoprotic Weak Acid a. Suppose that–unknown to you–the primary standard KHP (potassium hydrogen phthalate, KHC8H4O4) had a potassium iodide impurity of approximately one percent by mass. How would this have influenced the calculated molarity of your sodium hydroxide solution? Would your calculated value be too low, too high, or unchanged? Explain your answer. b. Sketch a typical titration curve for a monoprotic weak acid titrated with a strong base. Label the axes...
Use the data below to calculate the molar mass of an unknown monoprotic acid and submit a formal lab report via the assignment tab. A. Standardization Of NaOH Solution Please show all calculations: Trial 1 0.3555 g Trial 2 0.3545 g 17.46 mL 17.20 ml Mass of KHP Moles of KHP Volume of NaOH added Moles of NaOH Molarity of NaOH Average Molarity of NaOH % Difference between two readings
During the calculations for titration of vinegar experiment, you determined the molar mass of KHP by using the mass of K, H, and P instead of using KHC8H4O4. How would this change your results? Explain. We had to find the mass of KHP, moles of KHP, moles of NaOh, and moles of acetic acid, molarity of vinegar titrated, mass of acetic acid titrated in grams, and w/v % of acetic acid in vinegar
In this experiment, you will titrate an unknown acid with a base. It will be important for you to understand certain things about this titration in order to identify successfully your unknown. For all of the following questions, assume you are titrating an unknown monoprotic acid, HA, with NaOH solution. 0.146 g of HA is added to a beaker and made into a solution with ~100 mL of distilled water. As the titration proceeds, you keep track of the pH...
