Sodium carbonate (Na2CO3) also known as washing soda or soda ash is a sodium salt of carbonic acid. It is generally prepared by ammonia soda or Solvey process. A common source of sodium carbonate is the ashes of plants sometimes called soda ash.

production method alginic acid gel with content below 75% is made alkaline by adding 6-8% sodium carbonate solution, stir well, stand for 8H, filter, filter cake is boiled and dried to obtain sodium alginate. The yield was 20% by weight for kelp. Product Specification GB1976-80. raw ...
UsesNatural salt is the source of chlorine and of sodium as well as of all, or practically all, their Compounds, e.g., hydrochloric acid, chlorates, sodium carbonate, hydroxide, etc.; for preserving foods; manufacture of soap, to salt out dyes; in freezing mixtures; for dyeing and printi...
1 ml of Folin–Ciocalteu’s phenol reagent followed by 10 ml of sodium carbonate solution were added and the total volume was made to 25 ml by adding distilled water and left to react for 90 min. The optical density was determined at 750 nm and the quantity of total phenolic was calculat...
The van'tHoff factor of a 0.044 M aqueous solution of magnesium sulphate is 1.3. What is the freezing point of the solution if K_f = 1.86 degrees C/m? Why are molecules with double bonds more stable? If someone drank a slightly salty saline solution, what ...

concentrations are often used, as these have a much lower freezing point (e.g. 20% w/w freezes at −25°C). The chemical is often dosed in the as-delivered form. The use of carrier water to dilute chemical to around 0.5% w/w can help reduce precipitation ofcalcium carbonateat the...
