hello I was reading the latest question and I my attention went to "https://chemistry.stackexchange.com/questions/108367/does-dissolving-a-solid-in‌-water-change-its-specific-heat". IMHO the answer are correct and after reading a few lines I understood what it was about but it gets more understandable and easily if formulated as "is the specific heat of a solution different from the one of pure water".

I'm not an english speaker but "Does dissolving a solid in water change its specific heat?" refers to the solid or to the water? because formulated as it is my first answer would be "specific heat is peculiar of a substance.. the specific heat of a solution can be calculated as..." just curious to know your opinion and if eventually the title should be modified

@Jojostack The title is indeed a bit clumsy. It's correct in the body though: "Does dissolving something in water change the specific heat of the solution?" I'm going to change it.

Q: High concentration of ferric ion catalyst decreases rate of decomposition of hydrogen peroxide in the Fenton reaction

I did a project on the Fenton reaction and rate of decomposition of $\ce{H2O2}$. I used colorimetry to measure the rate of decolourisation of methylene blue when I mixed $\pu{5e-6 mol}$ $\ce{FeCl3}$ and $\pu{0.2 mL}$ of different concentrations of $\ce{H2O2}$ (1, 3, 5, 10, 15, and 20%). After pr...
