does taking 1 ml of solution y (pure bleach) out of the first beaker change the solutions concentration? what would the concentration of the second beaker be? if beaker #2 is a 1% solution of y, and beaker #3 is 1/100th of that in the final solution, what percentage solution would beaker #3 be? beaker #1 100 ml y beaker #2 99 ml h₂o beaker #3 99 ml h₂o

Answer

Explanation:

Step1: Determine if concentration changes

For a homogeneous solution, taking a small - volume sample does not change the concentration of the remaining solution. So, taking 1 mL of solution Y out of the first beaker does not change the solution's concentration.

Step2: Calculate concentration of Beaker #2

The amount of solute in the 1 mL of solution Y transferred to Beaker #2 is 1 mL of pure Y. The total volume of the solution in Beaker #2 after adding 1 mL of Y to 99 mL of water is (V = 99+1=100) mL. The concentration (C=\frac{1}{100}\times100% = 1%).

Step3: Calculate concentration of Beaker #3

If Beaker #2 is a 1% solution of Y and Beaker #3 is (\frac{1}{100})th of that in the final solution, then the concentration of Beaker #3 is (1%\times\frac{1}{100}=0.01%).

Answer:

  1. No
  2. 1%
  3. 0.01%
