CAS号:
性质:在等温等压的情况下,加1摩尔的纯溶剂于有限量和一定浓度的溶液中,所发生的热效应称为该条件下的积分稀释热,或简称稀释热。又称积分溶解热。例如: H2SO4(液)+nH2O(液)→H2SO4·nH2O △Hn H2SO4(液)+mH2O(液)→H2SO4·mH2O △Hm(m>n)其中,n及m分别为水的量(mo1),△Hn及△Hm分别为两个积分溶解热。把上二式相减,得 H2SO4·nH2O+(m-n)H2O→H2SO4·mH2O △H2O △Hm-n △Hm-n=△Hm-△Hn式中△Hm-n即为由H2SO4·nH2O加水稀释至H2SO4·mH2O的热效应,即稀释热(heat of dilution)。当一单位量的溶剂加到无限量的溶液中去,而溶液的组成基本上没有变化,所发生的热效应称为微分稀释热。
