What mass of NaCl is needed to form a saturated solution at 80C?
The saturated solution of sodium chloride is 379,3 g for 1 kg solution at 8o oC.
What is 10 pound brine water?
When water is saturated with sodium chloride (table salt) at standard conditions, the weight of one gallon of this saturated solution (brine) is 10 pounds.
Why is hypo used in photography?
Hypo is used in photography it is a solution of Sodium thio sulphate, Na2S2O3
How does the instant ice trick work?
A warm, saturated sodium acetate solution is allowed to cool. At the lower temperature the solution is supersaturated, meaning that more of a salt is dissolved in the water than would normally be possible. I the solution is disturbed the sodium acetate crystallizes instantly.
How do you prepare sea water solution?
Dissolve 30-40 g of sodium chloride in 1 L of water.
What is a bromin?
Sodium thiosulphate solution (5-25 %)
Why sodium carbonate is used in preparation of thiosulphate solution?
To ensure the stability of the solution
What is a bromine neutralizer?
Sodium thiosulphate solution (5-25 %)
Why is sodium thiosulphate used in iodometric titration?
· In analytical chemistry, sodium thiosulphate is used for the determination of the strength of a given solution of iodine. · Sodium thiosulphate is preferred in iodometric analysis due to the fact that sodium thiosulphate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents.
How do you prepare and standardize of 0.1 N Sodium Thiosulfate solution?
Dissolve 2.48818g of Na2s2o3.5h2o in frishly boiled distilled water. and add 2ml of chloroform for stability, it gives 0.01N sodium thiosulphate sol.
What is the use of Sodium thiosulphate in iodometry?
In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.
Why sodium thiosulphate solution is prepared in freshly boiled and cooled water?
why sodium thiosulfate to be prepared in hot water only
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
to acidify the solution
How is iodine estimated in ccl4 and h2o layer?
Titrate each solution separately with solution of known concentration of sodium thiosulphate. The titre value will give the amount of thiosulphate reacted with iodine, hence you can find concentration of iodine.
Is milk a saturated solution of sodium chloride?
No, it is not correct.
Is sodium thiosulphate solution a primary standard?
No. because it contains water of crystallization so it can absorb or release water..
0.1N Sodium Thiosulphate is primary or secondary solutions?
it is a secondary solution because it can change its concentration by absorbing moisture....
