Penentuan kelarutan dan H H2C2O4Pada suhu 27C = 300,15 KV1.N1 = V2.N24,25 mL.1,11 N = 10 mL. N2N2 = N2 = 0,4715 NM2 = = 0,2358 MS = M = 0,2358 M
T1 = 40C + 273,15 = 313,15 KT2 = 27C = 273,15 = 300,15 KH = log || 2,303 R + = log || 2,303x8,314 + = log 0,3085x 19,1471 0,000138 = -9,7794 J/mol
Pada suhu 37C = 310,15 KV1.N1 = V2.N25 mL.1,11 N = 10 mL. N2N2 = N2 = 0,555 NM2 = = 0,2775 MS = M = 0,2775 M
