The potassium permanganate is used to estimate oxalic acid, ferrous salts, hydrogen peroxide, oxalates and more. While the solution of potassium permanganate is always standardized before it is used. Dichromate Titrations These are titrations in which, potassium dichromate is used as an oxidising ...
Identification of Salts:By definition, if a compound is produced of either a cation or an anion, it is described as salt in chemistry. The simplest salts are the compounds of a kind of metal cation having one kind of non-metal anion. If we look at the periodic chart, there is a dark...

1. Is the topic of Azeotrope important, or can I skip it? It is an important topic of chemistry, and hence skipping it is going to be harmful to you, not only in the way of getting good marks in the exam but also in the future endeavours of chemistry as well. Hence, you should ...
High levels of sulphate salts can make water taste bad. Depending on the sulphate salts in the water, most people experience a disagreeable taste at 250–1,000 mg/L. High sulphate concentrations may reduce chlorination efficiency in some water supplies. Also, sulphate salts can make water more...

We prepared one-component solutions from MgCl2·6H2O or CaCl2·2H2O salts (Sigma-Aldrich, St. Louis, MO, USA). These solutions constitute the feed compartment, and their final concentrations of Ca2+ or Mg2+ vary from 10 mg·L−1 to 200 mg·L−1. As a receiver, we used NaCl solut...
