Hi, I been wondering why heat capacity increases after salt being added to pure water for a while. Based on the graph (page 89) provided by TBR, it also shows the heat capacity of water decrease after salt is added. The slope is steeper compared to the graph before salt is added. However, TBR says salt salvation increases heat capacity. In several passages, it also states heat capacity increases after salt is added. Today, I found a web page posted by an associate chem professor. In the page, he says salt lowers heat capacity and temperature changes at a faster rate compared to pure water. He says heat capacity for pure water is 4.18 while salt water is 3.93. He says the heat capacity is lowered due to disruption of the structure of water.
Here is the original webpage, if interested.

It is quite short. I think it would be helpful.
