To prepare a 0.05 Normal solution of sodium thiosulfate, you would dissolve the appropriate weight of sodium thiosulfate pentahydrate in a known volume of water to achieve a concentration that corresponds to 0.05 N. The molar mass of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) is 248.18 g/mol. You can calculate the weight needed using the formula: (Normality) x (Equivalent weight) x Volume = Weight of the compound.

What is thio group?
A thio group is a functional group in organic chemistry where a sulfur atom replaces an oxygen atom in a carbonyl group. It is commonly denoted as -S- in chemical structures. Thio groups can be found in compounds such as thioesters, thioamides, and thioketones.
What happens when sodium hydroxide and sulfuric acid are combined?
When sodium hydroxide and sulfuric acid are combined, they undergo a neutralization reaction to form sodium sulfate and water. The reaction is exothermic, meaning it releases heat energy. Both sodium hydroxide and sulfuric acid are strong bases and acids, respectively.
What is a major difference between thio and hydroxide neutralizers?
One major difference is their chemical composition: thio neutralizers contain sulfur while hydroxide neutralizers contain oxygen. Additionally, thio-neutralizers are generally used for neutralizing acidic wastewater, whereas hydroxide-neutralizers are typically used for neutralizing acidic gases or solutions.
What is the difference between thio and hydroxide relaxers?
Thio relaxers use ammonium thioglycolate to break the disulfide bonds in the hair, while hydroxide relaxers use hydroxide ions to break the disulfide bonds. Thio relaxers are milder and are often used on fine or damaged hair, while hydroxide relaxers are stronger and are better for coarse or resistant hair.
What is the Greek word for sulfur?
The Greek word for sulfur is θείο.
The hypo solution used in photography is the aqueous solution of?
Sodium thiosulphate (sulphate contains 4 oxygen atoms, thio-sulphate has one of these replaced by a sulphur atom). Dissolves away unexposed silver salts from photographic film or paper.
Why S-S bond is very weak in Thio sulphate ion?
cuz it do bruh
Why is hypo used in photography?
Hypo, or sodium thiosulfate, is used in photography to fix or stabilize the image on photographic paper by removing any unexposed silver halide. This process helps to make the image permanent and prevent further exposure to light from affecting the final print.
What is major difference between thio and hydroxide relaxers?
Hydroxide relaxers are not compatble with thio relaxers, permanent waving, or soft curl permanents because they use a different chemistry. Thio relaxers use thio to breake the disulfide bonds. The high pH of a thio relaxer is needed to swell the hair but it is the thio that breaks the disulfide bonds. Hydroxide relaxers have a pH that is so high that the alkalinity alone breaks the disulfide bonds.
