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.

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.
hypo
It reacts with water and a base called a hot aqueous alkali.
To prepare a hypo solution, dissolve sodium thiosulfate in water in a ratio of 1 part sodium thiosulfate to 5 parts water. Stir until completely dissolved. This solution is commonly used in photography to stop the development process.
aqueous
Hypo solution, also known as sodium thiosulfate solution, is commonly used in chemistry for iodometric titrations as a titrant to react with excess iodine after the reaction with the analyte. It is used to neutralize the excess iodine to determine the amount of analyte present in the sample.

The most commonly used measure of concentration for an aqueous solution is molarity, which is the number of moles of solute per liter of solution.
One example of a hypo-tonic solution used in intravenous infusion is 0.45% saline, also known as half-normal saline. This solution has a lower concentration of salt compared to the normal concentration in the body, making it hypo-tonic.
a dilute aqueous solution of KMnO4 may be used.
A hypo solution typically refers to a hypotonic solution, which has a lower concentration of solutes compared to a particular cell or tissue. When a cell is placed in a hypotonic solution, water will move into the cell, causing it to swell and potentially burst due to osmotic pressure.
Yes, NaOH (sodium hydroxide) is typically used in its aqueous form as a caustic alkaline solution.
