Sodium carbonate is a base. It will react with water in small amounts to produce hydroxide ions, which lowers the concnetration of hydronium ions, thus raising the pH.

Why is it important to to wash the crude cyclohexene with aqueous sodium carbonate?
The crude product is contaminated with water, unreacted alcohol
Why is it necessary to wash the crude cyclohexene product with aqueous sodium carbonate?

How do it get the smell out of new blue jeans?
Wash them , hirst in a solution of Washing Sode , Sodium carbonate (Na2CO3) , which is a very good smell romover. It will not discolour the blue. Then wash in ordinary washing machine detergent.
How do you treat a sodium hydroxide burn on tongue?
Wash with plenty of water / vinegar followed by water.
How do you get the sour smell from washed clothes?
Before primary washing in regular washing powder/soap. Soke the clothes in a solution of baking soda(Sodium bi-carbonate/sodium hydrogen carbonate) or Soda crystals(Washing soda/ sodium carbonate). Rinse Then wash in the normal detergent. If cotton or linen clothes, whilst wet/damp put them into laundry starch solution, hand squeeze dry, and allow to dry in the air. When dry , then iron/callender. (They'll be 'stiff as a board'. ) NB Sodium bi-carbonate or sodium carbonate, is a soluble salt, that will remove smells from many things, clothes, floors, drains, working surfaces. It is harmless to human skin, but wear kitchen gloves if needed, although it might make the skin a bit dry. Of itself it is odourless, white crystals. NB DO NOT use Bleech.
Does sodium carbonate decrease or increase the pH of the wash water?
The addition of baking soda (also known as sodium bicarbonate) to water decreases its pH value. This is because the base bicarbonate is particularly effective at neutralizing acidity.

Why was it necessary to wash the cyclohexene product with aqueous sodium carbonate?
The crude product is contaminated with water, unreacted alcohol, and some side products. Using sodium carbonate solution removes traces of acid

What are the ingredients in Oxyclean Is is bad for the environment?
The active ingredient is Sodium percarbonate. Sodium percarbonate breaks down to Hydrogen Peroxide (an oxidizer) and Sodium carbonate, which acts as a laundry detergent booster, by acting as a water softener. Also there is some Sodium Silicate in there. This ingredient bonds to heavy molecules and pulls them out of the wash water. It is fairly safe for the environment in moderate amounts. The carbonate is slightly caustic and hydrogen breaks down naturally.
How do you obtain pure crystals of sodium chloride when hdyrochloric acid is added to sodium hydroxide?
Sodium chloride is soluble in water, but zinc carbonate is not. Here is a procedure based on that simple difference in solubility. 1. Place the mixture in water and stir. The sodium chloride will dissolve. 2. Pour it through a filter. The insoluble zinc carbonate will remain on the filter, but the sodium chloride solution will pass through the filter. 3. Allow the water to evaporate from the sodium chloride solution. You are left with pure solid sodium chloride.
How do you separate calcium carbonate from sand?
Both the components in the mixture are insoluble in water. However, calcium carbonate reacts with hydrochloric acid to form calcium chloride (which is soluble in water) whereas the sand remains unchanged. Sand can now be separated by filtration. Calcium carbonate is recovered back by treating the filtrate (calcium chloride) with sodium carbonate. After filtration is again carried out, what you have on the filter paper is calcium carbonate.
Can oxyclean be used to wash a car?
Only if you're crazy...
What happen of mixed calcium chloride solution and sodium carbonate solution filtering and wash the residue with distilled water allow to dry adding hydrochloric acid?
Carbon dioxide gas is given out! Explanation: calcium carbonate precipitates from mixing calcium chloride solution and sodium carbonate solution, because it has low solubility in water. When it meets strong acid (HCl), it reacts to give out carbon dioxide while forming calcium chloride in the aqueous solution.

Why bicarbonate are soluble while carbonates are not?
If carbonates are not soluble, you will need to inform a number of laundries using sodium carbonate that it is no longer soluble and will no longer dissolve in wash water! While you are at it, you should do some research and find a different product they can use!
