Sodium thiosulfate pentahydrate ACS reagent, pH 6.0-8.4 (25 °C, 5% in solution), 99.5-101.0% | Sigma-Aldrich.

What is sodium thiosulfate?

Sodium thiosulfate is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio. It has a role as an antidote to cyanide poisoning, a nephroprotective agent and an antifungal drug. It contains a thiosulfate(2-).

Does sodium thiosulfate lower pH?

Test the pH of the pool after treatment with sodium thiosulfate. The chemical reaction with the chlorine and water lowers the overall pH of the pool, which can make it too acidic.

Is sodium thiosulfate an acid?

Thiosulfuric acid (as sodium thiosulfate) has the chemical name thiosulfuric acid, disodium salt, pentahydrate. The chemical formula is Na2S2O3•5H2O and the molecular weight is 248.17.

Why is sodium thiosulfate in salt?

In other words, there are three additives being combined with pure sodium chloride to make the final product: table salt. Sodium thiosulphate, from what I can find out, is added in very small quantities to help prevent the oxidization of the iodine.

What happens if alkalinity is high?

If your alkalinity level becomes too high, it will become difficult to change the pH. You’ll know your pH is too high when your pool water is cloudy, there is scale build up on your pool walls and your chlorine is no longer successfully sanitizing your pool.

Can I use peroxide in my pool?

Chlorine & hydrogen peroxide can mix together just fine. To start treatment, shock your pool with hydrogen peroxide by adding 250 ml (1 cup) of hydrogen peroxide for every 1000 liters (250 gallons) of water. To maintain a clean, sparkling pool, keep your hydrogen peroxide levels between 50 – 90 ppm.

How long can you live with calciphylaxis?

Calciphylaxis is a type of vascular calcification generally seen in patients with kidney failure. The condition causes skin lesions and severe pain and usually has a high mortality rate. Typically, patients diagnosed with calciphylaxis live about six months.

Is sodium thiosulfate a gas?

Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na2S2O3xH2O. Typically it is available as the white or colorless pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water.

Is sodium thiosulfate a strong or weak base?

In the case of thiosulfuric acid, the first ionization potential is in this category, so the basic properties of this salt is negligible. However, the second ionization potential of thiosulfuric acid is some less acidic and as such, the salt is a weak base. Consequently, sodium thiosulfate is a weak base.

What is the chemical name of thiosulfuric acid?

Thiosulfuric acid (as sodium thiosulfate) has the chemical name thiosulfuric acid, disodium salt, pentahydrate. The chemical formula is Na2S2O3•5H2O and the molecular weight is 248.17. Why is it called thiosulfate?) (IUPAC-recommended spelling; sometimes thiosulphate in British English) is an oxyanion of sulfur.

What is sodium thiosulfate used for?

Sodium thiosulfate is a chemical compound with the formula Na 2 O 3 S 2 or Na 2 S 2 O 3 . It is used as a drug to treat cyanide poisoning. It can also be used to counteract some other substances, as well.

What is the pKa of thiosulfate?

Since thiosulfate can be either monovalent (-1 charged) or divalent (-2 charged ) you need to know the strength of these acidic sites to answer your question. The strongest acidic site has a pKa of 0.6 while the second pKa is 1.72 (The smaller the pKa, the stronger the acid, extremely strong acids will have negative pKa values.
