Answer to Question #86332 in General Chemistry for tori

Question

The pH 10 buffer used involves mixing ammonia and ammonium chloride. What is the molar ratio of ammonia to ammonium chloride needed to produce a buffer with a pH of 10?

Answer 1

To find pH of the ammonia buffer we use the formula

.pH=14-p+lg

.lg = pH-14+p=10-14+4.75=0.75

=1=5.6
