undefined larutan undefined diencerkan dengan air hingga volumenya menjadi begin mathsize 14px style 2 end style liter, tentukan pH sebelum dan sesudahundefinedpengenceran!

Jawaban:

pH begin mathsize 14px style Ca open parentheses O H close parentheses subscript 2 end style sebelum pengenceran:

begin mathsize 14px style Ca open parentheses O H close parentheses subscript 2 open parentheses italic a italic q close parentheses yields Ca to the power of 2 plus sign open parentheses italic a italic q close parentheses plus 2 O H to the power of minus sign open parentheses italic a italic q close parentheses 0 comma 05 space M space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space left parenthesis 2 cross times 0 comma 05 right parenthesis space M space end style

Jadi, pH begin mathsize 14px style Ca begin bold style open parentheses O H close parentheses end style subscript bold 2 end style sebelum pengenceran adalah begin mathsize 14px style bold 13 end style dan pH begin mathsize 14px style Ca begin bold style open parentheses O H close parentheses end style subscript bold 2 end style sesudahundefinedpengenceran adalah begin mathsize 14px style bold 11 end style.
