Question

3. Suppose your unknown brass sample consists of a piece of hardware, such as a screw, and your lab is tasked with determining the copper content of the sample. One screw is not large enough to give a sufficiently concentrated solution of copper(II) ion when dissolved and diluted to 250 mL. Which of the following solutions would you choose to solve the problem?

3. Suppose your unknown brass sample consists of a piece of hardware, such as a screw, and your lab is tasked with determining the copper content of the sample. One screw is not large enough to give a sufficiently concentrated solution of copper(II) ion when dissolved and diluted to 250 mL. Which of the following solutions would you choose to solve the problem?

1. You dissolve two or more pieces of the same type and dilute to 250 mL.
2. You dissolve one piece, but dilute to a smaller volume.

Explanation / Answer

if the given screw is only one then in order to get concentrated solution it could be diluted to smaller volume than 250mL

Option 2) is correct

but if more than one pieces available than both methods could be employed.
