How can i determine the available chlorine in Sodium hypochlorite (Bleach) by titration with Sodium Thiosulfate?
To determine the available chlorine in sodium hypochlorite (bleach) using titration with sodium thiosulfate, first, dilute the bleach sample and then add an excess of potassium iodide, which reacts with the chlorine to form iodine. Next, titrate the liberated iodine with a sodium thiosulfate solution until a faint yellow color disappears, indicating that all iodine has reacted. The endpoint can be further refined with starch indicator, which changes color when iodine is fully reduced. Finally, calculate the available chlorine concentration based on the volume of sodium thiosulfate used in the titration.
What is the scientific name of sodium thiosulfate?
A white, translucent crystalline compound, Na2S2O3·5H2O, used as a photographic fixing agent and as a bleach. Also called hypo, hyposulfite; Also called sodium hyposulfite. Source: http://www.answers.com/sodium+thiosulfate?gwp=11&ver=2.3.0.609&method=3
What are the three components in order of administration used to treat cyanide exposure?
Amyl nitrite, sodium nitrite, sodium thiosulfate
How do you deactivate Bleach?
To deactivate bleach, you can neutralize it using a solution of sodium thiosulfate or a mixture of vinegar and baking soda. Sodium thiosulfate is commonly used in pools and can effectively neutralize chlorine. If using vinegar and baking soda, mix them in a well-ventilated area and apply the mixture to the bleach. Always take precautions, such as wearing gloves and ensuring proper ventilation, when handling chemicals.
What solution is produced when water and sodium thiosulfate will mixed?
A solution of sodium thiosulfate is produced.
Does bleach contain hydrogen peroxide?
No, bleach does not contain hydrogen peroxide. Bleach typically contains sodium hypochlorite as its active ingredient, which is different from hydrogen peroxide.
What is the valency of sodium thiosulphate?
The valency of sodium thiosulfate is determined by breaking down the compound into its constituent ions. In this case, sodium has a valency of +1 (Na+), and thiosulfate has a total charge of -2 (S2O3^2-). Therefore, the valency of sodium thiosulfate is +1 because it has one sodium ion for every thiosulfate ion in the compound.
How many atoms are in the molecule of sodium thiosulfate?
The molecule of sodium thiosulfate, Na2S2O3, contains 9 atoms in total.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
What is the reaction of sodium sulphite and sulphur?
When sodium sulfite reacts with sulfur, it forms sodium thiosulfate. This reaction typically involves the oxidation of sodium sulfite by sulfur to produce sodium thiosulfate.
Reaction of bromine with sodium thiosulfate?
When bromine reacts with sodium thiosulfate, it undergoes a redox reaction where bromine is reduced to bromide ions and thiosulfate is oxidized to form sulfate ions. The reaction can be used to titrate bromine in solution, as thiosulfate acts as a reducing agent, consuming the bromine until all the thiosulfate is oxidized.
What happens when sodium thiosulfate dissolves in water?
When water is mixed with sodium thiosulfate the surrounding area temperature decreases causing the temperature to become, colder. for example; the water is at 22.5 C when you mix it with sodium thiosulfate the temperature could decrease up to 19.5 C this is because sodium thiosulfate an endothermic reaction which makes new bonds with the water and the sodium thiosulfate
