What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
How is a solution of NaOH prepared dissolving 20g of NaOH in 500ml of distiled water solved?
To prepare a 20 g/500 mL solution of NaOH, you would gradually add 20 g of NaOH to 500 mL of distilled water while stirring until fully dissolved. It is important to add the solid to the liquid to prevent splattering. Remember to always use caution and appropriate personal protective equipment when handling NaOH due to its caustic nature.
What happens when an ester is reacted with NaOH?
When an ester is reacted with NaOH, it undergoes hydrolysis to form the corresponding carboxylate salt and alcohol. The reaction is typically called saponification and is often used in the production of soap.
What happens when a fatty acid is reacted with NaOH?
When a fatty acid is reacted with NaOH, a process called saponification occurs. This reaction results in the formation of soap, which is a salt of the fatty acid alongside glycerol. This reaction is commonly used in soap-making processes.
As edta dissolves in water the h will increase to achieve a pH 8.0 would you need to add hcl or naoh?
To achieve a pH of 8.0, you would need to add NaOH (sodium hydroxide) to increase the pH. NaOH is a strong base that will react with water to produce hydroxide ions, which will raise the pH. Adding HCl (hydrochloric acid) would lower the pH as it is a strong acid.
What happens when you add NAOH to Hydrogen?
Nothing.
What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
What happens if you swim in NaOH?
The alkali in NaOH would burn your skin.
What happens when sodium is add to 100 mL of water?
The chemical reaction is:2 Na + 2 H2O = 2 NaOH + H2
How do you neutralise on acid?
Add a base, such as NaOH, NH3, or LiOH
What happens when zinc add to alcoholic NaoH?
it makes a shirly temple with extra coke and grenadine spinkle some orange juice and thatis a alcoholic shirly temble with vitamin zinc
What happens when carbon dioxide is passed through NaOH solution?
2 NaOH(aq) + CO2(g) = Na2CO3(aq) + H2O(l)
What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?
You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.
What happen when zinc granules are add to NaOH?
In this case sodium zincate is formed.
What happens to sodium hydroxide when heated?
At very high temperature NaOH is decomposed and Na2O fumes are emited.The reaction is:2 NaOH = Na2O = H2O
