For the questions, assume that you start with 0.421 g of copper turnings: Calculate the minimum volume of 16.0 M HNO3 required to dissolve all of the copper (step 1). Answer: 1.66 mL   If, in practice, 5.0 mL of 16.0 M nitric acid were added to effect the dissolution of the copper (step 1), what would be the minimum volume of 4.00 M NaOH required to neutralize the remaining acid and convert all of the Cu2+(aq) to Cu(OH)2(s) (step 2)?

Consider the titrimetric determination of acetic acid (60.05 g/mol) in vinegar. Titration of a 5.00 mL vinegar sample requires 16.15 mL of 0.250 M NaOH to reach the phenolphthalein end point. What is the percent weight by volume of acetic acid in the sample?         2.97       4.85       6.01       7.44       None of the choices

The molarity of an aqueous solution of hydrobromic acid, HBr, is determined by titration with a 0.154 M sodium hydroxide, NaOH, solution. [Review Topics] [References] Use the References to access important values if needed for this question. HBr + NaOH → NaBr + H2O If 35.8 mL of sodium hydroxide are required to neutralize 20.7 mL of the acid, what is the molarity of the hydrobromic acid solution? Molarity M = Submit Answer Retry Entire Group 4 more group attempts remaining Previous

A chemist neutralizes 25.0 ml of a solution of H2SO4 with 25.0 mL of a 0.300 M solution of KOH. what is the molarity of the H2SO4 solution? Hint: start with a balanced chemical equation! 0.150 M 0.600 M None of these answers is correct

Question 8

A 24.8mL sample of vegetable juice is titrated with 15.65mL of NaOH solution. The molar concentration of the NaOH is .106 M. The molar mass of citric acid is 192.12 g-mol-1. Express all with three significant figures.  A) Determine the molar concentration of citric acid in the vegetable juice sample B) Determine the number of moles of citric acid per 240 mL of the vegetable juice.  C) Determine the mass of citric acid per 240 mL of the vegetable juice.  D) If the label on the bottle lists the citric acid contest as 1g per serving with a serving size of 240 mL determine the percent error in the rotation results. Express in 2 sig figs.

what is the molarity of a solution of phosphoric acid (a tricrotic acid) if 10.00 mL of the phosphoric acid solution requires 38.11 mL of 0.2412 M NaOH solution to titrate it?

If 25.0 mL of 0.1000 M HCl is titrated with NaOH with an initial volume of 3.02 mL and final volume of 24.10 mL, what is the concentration of the NaOH (in M)?

What is the concentration of a solution of HCl in which a 10.0 mL sample of acid required 50.0 mL of 0.150 M NaOH solution for neutralization?
