Hidrolisis asam adalah larutan garam hidrolisis yang terbentuk dari campuran larutan asam kuat dengan larutan basa lemah. Menentukan konsentrasi ion pH = 4 pH = - log 4 =- log = antilog Menentukan konsentrasi kationgaram Menentukan konsentrasi Menentukan Mr Menentukan massa garam hidrolisis Jadi, massa yang terlarut adalah 107 gram
