Sodium thiosulphate neutralises chlorine, so preventing further bactericidal effects on organisms in the water during transit to the laboratory. (ie. results of analysis will be representative of sample at time of sampling.)

What substance is being oxidized when sodium reacts with chlorine gas?

In this reaction, sodium is being oxidized. When sodium reacts with chlorine gas, sodium atoms lose electrons to form sodium ions, and this process involves the loss of electrons, which is characteristic of oxidation.


Equation between potassium iodate and sodium thiosulphate?

The equation between potassium iodate (KIO3) and sodium thiosulfate (Na2S2O3) involves a redox reaction. In the presence of an acid, potassium iodate is reduced to iodine (I2), while sodium thiosulfate is oxidized to form sodium tetrathionate (Na2S4O6). The balanced chemical equation for this reaction is 5Na2S2O3 + 2KIO3 + 8HCl → 5Na2S4O6 + 2I2 + 2KCl + 6H2O.


Sodium Na 11 stable or radioactive?

Sodium primarily exists as stable sodium-23, which is the most common and stable isotope of sodium. However, sodium can also form radioactive isotopes, with sodium-22 being a well-known example that is radioactive.


What is the formula Na3 PO4?

Sodium Phosphate why because you first would separate Na or sodium being a metal and the charge of it being +1 or the oxidation number then PO4 is a compound being Phosphate charge -3 then all you would do is criss cross them to find name of compound simply it be Sodium and Phosphate


What is the opposite of Chlorine on the periodic table of elements?

The opposite of Chlorine on the periodic table of elements is Sodium. Chlorine is a halogen located in group 17, while Sodium is an alkali metal located in group 1. They are opposite in terms of their properties and reactivity, with Chlorine being a nonmetal and Sodium being a metal.

What happens when sodium peroxide comes in contact with sodium thiosulfate?

An exothermic reaction will occur, with the peroxide being reduced and the thiosulfate being oxidized.


What type of chemical reaction when sodium thiosulphate is dissolving in water?

When sodium thiosulfate dissolves in water, it undergoes a physical change rather than a chemical reaction. The sodium thiosulfate molecules are surrounded by water molecules, causing them to separate and disperse throughout the solution. This process is known as dissolution, where the ionic compound breaks apart into its constituent ions without any chemical bonds being broken or formed.


What does potassium thiosulfate weigh?

As a liquid, it weighs 12.2 pounds per gallon.


What is a microbiological safety cabinet used for?

Microbiological safety cabinets provide an enclosed environment for lab technicians to work within without the risk of microbe release. There are varying levels depending on the work being performed and the microbes being used.


Why thiosulphate titration is called as redox titration?

A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.


What chemical used in clorine testing in water?

The chemical commonly used for testing chlorine in water is sodium thiosulfate. This chemical is added to water samples that are being tested for chlorine content to neutralize the chlorine and allow for accurate measurement using colorimetric methods.


What is the effect of adding sulfuric acid in iodimetry titration?

Adding sulfuric acid in iodimetry titration helps to oxidize iodide ions to iodine, which is then titrated with a standard solution of sodium thiosulfate. Sulfuric acid also prevents the interference of other reducing agents that may be present in the sample being tested.

What does container architecture refer to?

Container architecture refers to the designing of structures using steel shipping containers. These shipping containers are usually seen on ships or being unloaded at the ports. However, people have found that they can build houses or other buildings by using shipping containers that are no longer being used for transport.
