SUMMARY

The discussion focuses on calculating the pH of a solution containing 50.0 mL of 1.00M hydrochloric acid (HCl) and 50.0 mL of 1.00M hydrofluoric acid (HF). The concentration of both acids in the final solution is determined to be 0.5M. Complete dissociation of HCl is assumed, while the dissociation of HF is evaluated using its acid dissociation constant (Ka). The total concentration of hydrogen ions (H+) in the solution is calculated to determine the pH.

PREREQUISITES
  • Understanding of strong and weak acids
  • Knowledge of acid dissociation constants (Ka)
  • Ability to perform molarity calculations
  • Familiarity with pH calculations
NEXT STEPS
  • Research the acid dissociation constant (Ka) for hydrofluoric acid (HF)
  • Learn how to calculate pH from hydrogen ion concentration
  • Study the concept of complete vs. partial dissociation in acids
  • Explore buffer solutions and their pH calculations
USEFUL FOR

Chemistry students, educators, and professionals involved in acid-base chemistry or pH calculations in solutions.

Homework Statement


Find the pH in 50.0 mL of 1.00M HCl + 50.0 mL of 1.00M HF

Homework Equations


None to speak of really...

The Attempt at a Solution


I figured out [HCl] and [HF] in the solution: they're both 0.5M.
I have absolutely no idea what to do at this point... Thanks.

Are you given the Ka for HF? If so, you can assume complete dissociation of HCl and use the given data to find the degree to which HF dissociates. Thus you can find the total no. of moles of H+ in the solution.
