Sodium sulfate. Sodium sulfate is the sodium salt of sulfuric acid. With an annual production of 6 million tonnes, it is one of the world's major commodity chemicals. Anhydrous, it is a white crystalline solid of formula Na 2 SO 4; the decahydrate Na 2 SO 4 ·10H 2 O has been known as Glauber's salt or, historically, sal mirabilis since the ...
Mar 22, 2013 · The main sulfate – carbon reactions and the subsequent reaction of sulfate with the Na 2 S and CaS formed and SO 2 and S release occur simultaneously at 500°C. Sodium sulfate accelerates glassmaking and fining in two stages. The first stage proceeds at 500 – 800°C and is due to the formation of low-melting eutectics.
May 15, 2023 · Sodium Sulfate: Structure, Properties, and Chemical Reactions. Sodium sulfate is a chemical compound that resembles white powder and is very water-soluble. Additionally, there are several additional sodium sulfate varieties with different water crystallization. Sodium sulfate has the chemical formula \ (\mathrm {Na}_2 \mathrm {SO}_4\).
cooking (7). The importance of mechanical pulps and of non-wood pulps should also be noted. Kraft cooking conditions in general – the significance of sulfide in the cooking liquor The active cooking chemicals in kraft cooking are sodium hydroxide and sodium sulfide, usually represented by active alkali (all NaOH and all Na
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white ...
May 30, 2019 · Sodium bisulfate is also known as sodium hydrogen sulfate. This is an acid salt that is formed when sulfuric acid is partially neutralized with a sodium base, such as sodium chloride or sodium hydroxide. It is an acidic substance that has a pH of around 1, and it usually comes in a dry, granular form.
