[Chemistry] How do you find the new concentration?

Click For Summary
SUMMARY

The discussion centers on calculating the concentration of solution B after mixing 10 mL of solution A (7.00x10^-4 mol/L) with 10 mL of 0.1M HCl. The correct approach involves determining the moles of solute in both solutions and then dividing the total moles by the total volume of the mixture. It is crucial to consider whether HCl reacts with any components in solution A, as this could affect the final concentration.

PREREQUISITES
  • Understanding of molarity and concentration calculations
  • Knowledge of stoichiometry in chemical reactions
  • Familiarity with dilution principles
  • Basic chemistry concepts regarding acid-base reactions
NEXT STEPS
  • Calculate the moles of solute in solution A using the formula: moles = concentration × volume.
  • Determine the moles of HCl in the 10 mL of 0.1M solution.
  • Research the potential reactions between HCl and components in solution A.
  • Learn about dilution calculations and their impact on concentration changes.
USEFUL FOR

Chemistry students, educators, and professionals involved in laboratory work or chemical analysis who need to understand concentration calculations and the effects of mixing solutions.

Homework Statement


For solution A the concentration is 7.00x10^-4 mol/L. You transfer 10ml of the solution A out into a 10 dram vial and add 10mL of 0.1M HCL acid solution, and the new mixture is called solution B. What is the concentration of solution B?



Homework Equations


The Attempt at a Solution



is this right approach? first find the mol of solution A, and then find the mol of HCl. Add them together and divided by the total volume.

Thanks.

I guess it would depend on if the HCl would react with the material in the stock solution.
