Ferrous ammonium sulphate is a double salt known as Mohr’s salt. In this titration, potassium permanganate acts as an oxidizing agent and Mohr’s salt acts as a reducing agent. … In this redox reaction, ferrous ions from Mohr’s salt get oxidised.
What type of reaction is ammonium sulfate?
Reactions. Ammonium sulfate decomposes upon heating above 250 °C, first forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water. As a salt of a strong acid (H2SO4) and weak base (NH3), its solution is acidic; pH of 0.1 M solution is 5.5.

Is Ferrous ammonium sulphate a base or acid?
Ammonium sulphate is a salt from a strong acid and a weak base thus is an acidic salt. So, the correct answer is “Option C”.
What does DPD test for?
The DPD test is used extensively in water treatment to determine the level of disinfectant present. In most cases this is Free Chlorine but it can be used to measure other parameters ( oxidants ). It is a quick and relatively easy test which requires little background or skill to perform.
What is DPD method?
A method of measuring the chlorine residual in water. The residual may be determined by either titrating or comparing a developed color with color standards. DPD stands for N,N-diethyl-p-phenylenediamine.
