Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
How many grams of NaOH are in 750 ml 0.600 M NaOH solution?
This solution contain 26,3 g NaOH.
What is the molarity of a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
Purpose of adding NaOH to the mixture before taking the polarimeter reading?
To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
What is the solution of NaOH in methyl orange indicator?
Methyl orange shows yellow color in an NaOH solution.
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
What would happen when sodium hydroxide is placed in salt water?
Nothing; other than; adding Solid NaOH or diluting a solution of NaOH with NaCl solution, will produce energy, resulting in a temperature increase.
What is the purpose of adding NaOH to the mixture before taking the polarimeter reading?
It is to neutralize the solution and to stop the hydrolysis.
Why is NaOH heated before adding BaCl2?
By adding HCl, you can ensure the presence of the SO4(2-) ion.
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
Can I lower the pH of sodium hydroxide with water?
Yes. Adding water to a solution of sodium hydroxide will dilute the NaOH and lower the pH.
How many grams of NaOH are in 750 ml 0.600 M NaOH solution?
This solution contain 26,3 g NaOH.
Purpose of adding NaOH to the mixture before taking the polarimeter reading?
To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
Can we make 1N NaOH solution from 0.1N NaOH solution?
It is possible only if you evaporate the water.
What is the molarity of a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
How is a solution of NaOH prepared dissolving 20g of NaOH in 500ml of distiled water solved?
The concentration of this solution (in NaOH) is 40 g/L.
How an exact of 0.1N solution of NaOH can be prepared?
standardization of NaoH
