How to calculate heat of dilution
Web18 jun. 2024 · In Caustic Soda Handbook of OxyChem, there is an example saying "the approximate resulting temperature of final solution after diluting 50 % N a O H at 120 ∘ F ( 48.9 ∘ C) to 20 % using water at 80 ∘ F ( 26.7 ∘ C) is 143 ∘ F ( 61.7 ∘ C )." This would result 63 ∘ F ( 35 ∘ C) raise with respect to water temperature. WebDilution is the process of decreasing the concentration of a solute in a solution, usually simply by mixing with more solvent like adding more water to the solution. To dilute a solution means to add more solvent without the addition of more solute. The resulting solution is thoroughly mixed so as to ensure that all parts of the solution are identical.
