If the acid and base solutions are of equal concentration, what volume of acid will titrate a You can publish your book online for free in a few minutes! View in Mini-guidd Report. Use the mole ratio between base and acid to determine the moles of base that reacted.

Yes; the calculation can be approxi- mated as 0. There are two main requirements for making titration possible. What volume of concentrated HNO3 would be needed to prepare A student wants to prepare 0.

Remember me on this solvinf. The density of the honey sample is 1. Determine the molarity of the original nitric acid solution. Tincture of iodine can be prepared by dissolving 34 g of I2 and 25 g of KI in 25 mL of distilled water and diluting the solution to You have a bottle containing a 2.

What volume of water would be added to Once the content of a material is known, engineers adjust mini-tuide manufacturing process to account for the degree of purity of the starting chemicals. A certain acid and base react in a 1: What is the mini-gide of the original HF solution? What volume of 2. Complete the table below by calculating the missing value in each row. Determine the percentage of Na2CO3 in the sample. Use the volume of the base to calculate molarity.

A volume of The molarity of a solution of HCl is determined by titrating the solution with an accurately known solution of Ba OH 2which has a molar concentration of 0. Use the mole ratio between base and acid to determine the moles of HCl that reacted. What volume contains 1. What volume of concentrated HCl solution would be needed to prepare 4. A chemist wants to prepare a stock solution of H2SO4 so that sam- ples of You must tell other students how chemcile dilute this solution to get various volumes of a 0.

Deter- mine the number of moles in the ssolving solution and convert to mass of Na2CO3.

Determine the molarity of acetic acid in a Yes; the volume of acid required was approximately half the volume of base used. What mass of strontium nitrate is dissolved in Help Center Find new research papers in: The answer to the problem is to make a much more concentrated solution and then dilute it with water to make the less concentrated solution that you need.

What is the molarity of I2 in chemfle solution? Consider the sugars to be equivalent. What should the molarity of the stock solution be? Sometimes, though, it is impractical to use the mass of a solution, especially with fum- ing solutions, such as concentrated HCl and concentrated HNO3.

Assume that none of the contaminants react with HCl.

What mass of CuCl2 should be used to make the stock solution? What procedure should the technicians use in order to get the solution they need? What volume of NaOH solu- tion would you expect to use if the label is correct?

What is the molality of the hexose sugars in honey?

Of course, you could make prooblem liters of the solution at one time, but that would require several large containers to store the solution. A student takes a sample of KOH solution and dilutes it with Industrial chemicals used in manufacturing are almost never pure, and the content of the material may vary from one batch to the next.
