During a typical precipitation process, as shown in Figure 4.18, sulphuric acid and sodium silicate are continuously added to a mixture of water already containing a little sodium silicate. The presence of the sodium silicate in solution to begin with helps to buffer the initial addition of the acid …
In this experiment an insoluble metal oxide is reacted with a dilute acid to form a soluble salt. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution. From this solution, blue copper(II) sulfate pentahydrate crystals can be obtained.
Copper(II) sulfate, also known as copper sulphate, are the inorganic compounds with the chemical formula Cu SO 4 (H 2 O) x, where x can range from 0 to 5. The pentahydrate (x = 5) is the most common form. Older names for this compound include blue vitriol, bluestone, vitriol of copper, and Roman vitriol.

For metals with variable valence, the metaborate changes to lower valence state. For example, with copper sulphate, the borax bead test gives, In oxidizing flame: In reducing flame:
Jul 01, 2015· For some time in the nineteenth century, sodium sulfate was manufactured from sodium chloride and sulfuric acid in the Leblanc process, as an intermediary to meet a rising demand for sodium carbonate, until the manufacture was wiped out by the superior Solvay process.
Bulking agents, such as sodium sulfate and water. Some detergents need anti-caking agents, for example aluminium silicate, which keep the powder dry and free-flowing. Builders, usually sodium aluminosilicates, a type of zeolite, remove calcium and magnesium ions and prevent the loss of surfactant through scum formation.

Why do you add an excess of copper carbonate to sulfuric acid when preparing the salt copper sulphate? Because some of the copper carbonate will evaporate in the form of carbon dioxide.
Formerly, sodium sulfate was also a by-product of the manufacture of sodium dichromate, where sulfuric acid is added to sodium chromate solution forming sodium dichromate, or subsequently chromic acid. Alternatively, sodium sulfate is or was formed in the production of lithium carbonate, chelating agents, resorcinol, ascorbic acid, silica ...
1. Sodium sulfate Uses in Chemical Industry. In the chemical industry, this sal mirabilis main functions are as raw material to create another chemical compound that we needed.Through some process and mechanism, sodium sulfate is commonly 'baked' into sodium sulfide, sodium silicate…
Sulfuric acid is one of the most commonly used acids on the planet, according to its MSDS. It is also used in making fertilizer and in a wide range of chemicals and in research. Potassium sulfate, which is made when potassium hydroxide and sulfuric acid are combined, is used in fertilizer and also to make glass and aluminum.
It is also prepared by treating oxides of copper with dilute sulfuric acid. Gradual leaching of low-grade copper ore in the presence of bacteria under aerobic conditions can produce copper sulfate. Copper sulfate used for commercial purposes is 98% pure. Anhydrous Copper sulphate is 60.19% sulfate and 39.81% copper by mass.
We are offering sodium sulphate. We put forth a wide gamut of superior quality sodium acid sulphate, which is the sodium salt of sulphuric acid. This is mainly used in the preparation of detergents as well as in the kraft process of paper pulping. It is a white crystalline solid and is odorless in nature.
