Question
Part A Express your answer numerically to two decimal places. pH = 11.39 Correct pH = 11.39 11.39 Correct Part B What is the percent ionization of ammonia at this concentration? Express the percentage numerically to three significant figures. Part B What is the percent ionization of ammonia at this concentration? Express the percentage numerically to three significant figures. Ammonia, , is a weak base with a value of . Part A What is the pH of a 0.330 ammonia solution? Express your answer numerically to two decimal places. pH = 11.39 Correct Part B What is the percent ionization of ammonia at this concentration? Express the percentage numerically to three significant figures.Explanation / Answer
let the degree of ionistion be k.so,
1.8*10^-5=0.33k^2/(1-k)
or k=0.007358
so percentage ionisation=100k
=0.7358%
pOH=
so pH=11.382.614
