Description
도 2는 몰랄 농도 및 온도의 함수로서 두 알칼리제에 대한 순수한 물에서 용해 누적열을 나타낸다. 도 2에서 상부 그래프는 Ca(OH)2를 나타내고, 하부그래프는 NaHCO3를 나타낸다.
도 3은 3M 당량 산 용액이 중화될 때 방출되거나 흡수되는 총 반응열을 나타낸다. 도 3에서 상부 그래프는 Ca(OH)2를 나타내고, 하부그래프는 NaHCO3를 나타낸다. 각 반응 별로 다른 색으로 표시되고 순 반응열은 흑색선으로 표시된다. 청색선 및 적색선은 각각 초기 온도에서 변화하는 온도의 예측값 및 실험값을 나타낸다.
도 4는 1.5M H2SO4용액에 첨가되는 알칼리제의 증가량에 따른 석고, 무수 석고, 반수 석고, 미라빌라이트 및 세나다이트의 계산된 SI 프로파일을 나타낸다. 도 4에서 상부 그래프는 Ca(OH)2를 나타내고, 하부그래프는 NaHCO3를 나타낸다.
도 5는 4개의 40wt% 산 용액(HCl은 37wt%)이 Ca(OH)2에 의해 중화될 때 방출되는 총 열(흑색선) 및 각 반응의 반응열을 나타낸다.
