WebMay 3, 2013 · Why the enthalpy change of hydration of anhydrous magnesium sulphate cannot be measured directly? Because this kind of reaction is usually not spontaneous. … WebFeb 2, 2024 · The results confirm the presence of copper and reveal that Cu(II) is not adsorbed solely as a precipitate of copper sulfate. The ratio of Cu(II) to S in copper sulfate is ~2:1, while EDX results showed the ratio of 4.2:1. In other words, copper is chelated through active sites of the adsorbent—mainly the sandwiching of Cu(II) between electron ...
