The acid ionization equilibrium for the weak acid HF is represented by the equation below. To prepare a buffer with a pH=3.50 , a student needs to mix 250.mL of 0.100MHF and 250.mL of 0.100MKF . If the student mistakenly mixes 250.mL of 0.0500MHF and 250.mL of 0.0500MKF , which of the following is the result of this error? *
