What type of chemical reaction when sodium thiosulphate is dissolving in water?
Dissolution.
What are the chemical present in salt?
salt is also called sodium chloride. sodium is a mineral on the periodic table, and so is chlorine. sodium + chlorine gas = salt sodium and chlorine are fatally dangerous, but when put together, they make something completely harmless and useful.
What type of chemical reaction occurs when sodium and chloride combine to form sodium chloride?
A strongly exothermic reaction to produce a salt, sodium chloride.
How are sodium and chlorine used today?
Sodium is used in salt. Chlorine, small amounts are used in drinking water.
Why is chlorine and sodium dangerous?
Sodium is dangerous because it is an Alkali metal which is HIGHLY reactive with water. Chlorine is dangerous because it forms a strong acid with water.
What type of chemical reaction when sodium thiosulphate is dissolving in water?
Dissolution.
What is the chemical formula for sodium thiosulfate and water?
Sodium Thiosulphate is Na2S2O3 and water is H2O.
Why is sodium thiosulfate being put in microbiological water containers?
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.)
Why sodium thiosulphate solution is prepared in freshly boiled and cooled water?
why sodium thiosulfate to be prepared in hot water only
What does sodium thiosulphate and hydrochloric acid react to form?
sodium chloride, sulphur, sulphur dioxide and water
What are the chemical present in salt?
salt is also called sodium chloride. sodium is a mineral on the periodic table, and so is chlorine. sodium + chlorine gas = salt sodium and chlorine are fatally dangerous, but when put together, they make something completely harmless and useful.
Do you have to heat the sodium and chlorine mixture to get salt?
If you place elemental sodium and elemental chlorine together, yes you will have to add significant amounts of heat to catalyzed the reaction. This would also be extremely dangerous as elemental sodium is extremely reactive with water and elemental chlorine is toxic.
Sodium chloride is mixed with water?
When NaCl is placed in water, the sodium and chlorine dissociate, giving you ions of chlorine which are negatively charged, and sodium ions which are positively charged. There is no reaction when sodium chloride is placed in water.
Is sodium thiosulphate solution a primary standard?
No. because it contains water of crystallization so it can absorb or release water..
Is it a good idea to mix sodium and chlorine to create sodium chloride?
Firstly you have to go through two precursor steps before this can be achieved as putting sodium and chlorine together straight away isn't advisable.Sodium can be put into water to create sodium hydroxide and chlorine can be reacted with hydrogen to produce hydrogen chloride. These two reactants can then be used to create sodium chloride.2Na + 2H2O ---> 2NaOH + H2.H2 + Cl2 ---> 2HClNaOH + HCl ---> NaCl + H2ONotice that if you did add sodium and chlorine together in situ, then just by adding water to the situ mix, then the reaction could look to be self sustaining as long as you had enough sodium and chlorine. Therefore water would be considered as a catalyst for this reaction as it starts the reaction but it always returns to its original form, the classic definition of a catalyst.
What demonstrates a synthesis reaction?
The formation of water form hydrogen and oxygen: 2H2 + O2 --> 2H2O The formation of sodium chloride from sodium and chlorine: 2Na + Cl2 --> 2NaCl
What type of chemical reaction occurs when sodium and chloride combine to form sodium chloride?
A strongly exothermic reaction to produce a salt, sodium chloride.
