A 1.00 liter solution contains 0.33 M hydrofluoric acid and 0.25 M sodium fluoride. If 25.0 mL of water are added to this system, indicate whether the following statements are true or false, (Note the the volume MUST CHANGE upon the addition of water.) A. The concentration of HF will increase. eg ME NO M True False M B. The concentration of F will remain the same. BC. The equilibrium concentration of H30+ will increase. D. The pH will remain the same. M rea E. The ratio of [HF] / [F] will decrease. re Sol A A 1.00 liter solution contains 0.38 moles hydrocyanic acid and 0.29 moles sodium cyanide. If 0.15 moles of hydrobromic acid are added to this system, indicate whether the following statements are true or false.
