Copper sulphate add to sodium hydroxide result colour?
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
When do you add sodium hydroxide into the conical flask containing the analgesic?
when the solution turns blue you add the sodium hydroxide (also if it is not blue you have gone wrong stupid)
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What happen if you add the copper sulphate to sodium hydroxide?
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
When 10g of sodium is put into 100g of water the reaction produces 109.6g of sodium hydroxide solution why does it not add up?
When 10g of sodium are put into 100g of water, the reaction produces only 109.6g of sodium hydroxide because of the sodium's solvency. Some of the sodium is displaced in the reaction, and this is why it does not seem to add up.

A chemical reaction occurs between sodium hydroxide and hydrogen chloride Adding more sodium hydroxide to the reaction causes it to speed up If you add more of a reactant such as sodium hydroxide?
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
What do you add to sodium hydroxide to get pH lower?
Acid
What is the color produced when you add the phenolphthalien to sodium hydroxide solution?
You will get a pink to a pinkish-red solution depending on how concentrated the sodium hydroxide (NaOH) is.
How do you saponify Oleic Acid?
add sodium or potassium hydroxide.

What are the steps to do the biuret test?
1) Add 2cm3 of solution to be tested to a test-tube. 2) Add an equal volume of 5% potassium hydroxide* solution and mix. 3) Add 2 drops of 1% copper sulphate solution and mix. A mauve or purple colour develops if protein is present. *Sodium hydroxide solution can be used instead of potassium hydroxide solution.
What is the reaction of sodium hydroxide and sodium bisulfite?
There will not be any reaction .Both will remain togather in mixed form i.e.Na+ OH- and HSO3 ions in aquaeous solution Dr. Pradhan As a matter of fact there will be a reaction. Sodium Bisulfite (Sodium Hydrogen Sulfite) is a weak acid and Sodium Hydroxide is a Strong Base. Sodium Hydroxide will convert the Sodium Bisulfite to Sodium Sulfite (Na2SO3). You can actually see the reaction take place as Bisulfite generally has a yellow tinge to it, when you add NaOH the yellow tinge disappears and the solution turns clear and colorless. Chris D.
How do you make a 5 percent water solution of sodium hydroxide?
Add 5 g of sodium hydroxide to 95 g (or 95 mL) of water to get a 5% solution.
