to wash out any traces of acids...handy if your working with phenols....
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.
Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
How do you dispose of Potassium Chloride that is out dated?

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.

Why did you not wash the crude t-pentyl chloride with aqueous sodium hydroxide?

What does it mean that Wash organic layer with 1.0 ml of 1M aqueous sodium bicarbonate?
1m is the molarty of the solution meaning the concentration is 1 mol of baking soda (sodium bicarbonate) to every liter of water. 1 mol of sodium bicarbonate is 84g. so for 1ml of water with a molarity of 1 divide 84g by 1000 which is 84mg and add that to 1ml of water. as far as wahing the organic layer i think it means washing any water from the solution but i may be wrong idk.
