Tentukan titik didih larutan jika 22,2 gram CaCl2 (Mr=111)dilarutkan dalam 200 gram air (Kb=0,52)
yeolawu
Tb pelarut = 100 ( karena air) i = 3 ( cacl2 adl elektrolit) delta Tb = m x kb x i delta Tb = 22.2/111 x 1000/200 x 0.52 x 3 delta Tb = 0.2 x 5 x 1.56 delta Tb = 1.56 delta Tb = Tblarutan - Tbpelarut 1.56 = Tb larutan - 100 Tb larutan = 101.56
