Why sodium was not discovered until 1807?
Sodium is a highly reactive element that is not found in its pure form in nature, making it difficult to isolate. In 1807, Sir Humphry Davy was able to isolate sodium by electrolyzing sodium hydroxide, allowing for its discovery. Prior to this, sodium compounds were known, but the element itself had not been isolated.
How Make up a 7.5 percent solution of sodium carbonate in water?
To make a 7.5% solution of sodium carbonate in water, add 7.5 grams of sodium carbonate to 100 mL of water and stir until the sodium carbonate is completely dissolved. This will give you a 7.5% (w/v) solution of sodium carbonate.
Why is sodium packed in polythene?
Sodium is packed in polythene to prevent it from reacting with air or moisture, which could lead to degradation and reduced effectiveness of the substance. The polythene helps to create a barrier that keeps the sodium away from these elements, thus ensuring its stability and purity until it is ready for use.
Reaction of bromine with sodium thiosulfate?
When bromine reacts with sodium thiosulfate, it undergoes a redox reaction where bromine is reduced to bromide ions and thiosulfate is oxidized to form sulfate ions. The reaction can be used to titrate bromine in solution, as thiosulfate acts as a reducing agent, consuming the bromine until all the thiosulfate is oxidized.
What is a word equation for the reaction of sodium and water?
Sodium reacts exothermically with water. When it reacts small pea-sized pieces will bounce across the surface of the water until they are consumed by it, whereas large pieces will explode. While sodium reacts with water at room temperature, the sodium piece melts with the heat of the reaction to form a sphere, if the reacting sodium piece is large enough. The reaction with water produces very caustic sodium hydroxide and highly flammable hydrogen gas.
Why was soduim not extracted until 1807?
Sodium was not extracted until 1807 because it is a highly reactive element that is not found in its pure form in nature. The extraction process required the development of new techniques and equipment to handle its reactivity, which were not available until then. Humphry Davy was the first to successfully extract sodium using electrolysis.
How do you dissolve Sodium solfate?
To dissolve sodium sulfate, simply add it to water and stir until it is fully dissolved. Sodium sulfate is highly soluble in water, so it should dissolve easily without the need for additional solvents or heat.

Why was sodium not extracted until the 1800s while gold has been used for thousand of years?
Gold exist as native element, with a specific color, is not reactive - as a consequence it is simply to be identified. Sodium is very reactive, form many minerals and methods to be separated doesn't exist before 1 800.
If a Buddhist experienced suffering how would he explain it?
Suffering is a normal condition. If you have a body, you will experience suffering. There is no escaping suffering until you become fully awakened and leave your physical body behind. Buddha describes the path to become fully awakened. Full awakening and natural events will eventuate complete freedom from suffering. Buddhists are not free of suffering any more than anyone else, until they have an awakening experience. Then, suffering will begin to diminish, however, suffering does not fully extinguish until one if fully awakened and left the body.
Why sodium discovered until 1807?
The process of electrolysis had to be invented before sodium could be separated. That process was not invented until 1807.
How do you prepare 1 percent of sodium citrate?
To prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
How do you scramble a string in java?
Take out one letter, using a random number. Then replace the string with the new string, without the extracted letter. Repeat, until the remaining string has a length of zero. The extracted letters get added to a new string.Take out one letter, using a random number. Then replace the string with the new string, without the extracted letter.

How do you liquidify powdered sodium hydroxide?
To liquidify powdered sodium hydroxide, you can dissolve it in water. Slowly add the powder to water while stirring gently until fully dissolved. Be cautious as this process is exothermic and generates heat, so allow the solution to cool before use.
Why sodium carbonate is not a chemical change?
Sodium carbonate is a compound. Until you react it with something, it cant have or be a chemical change.
Did russia compete fully in the Olympics until 1952?
No
How do you make dry ice with sodium acetate?
You have to boil and heat water and add sodium acetate (a powder easy to find online), and mix it until it is fully dissolved. Then pour the water in a glass and put the glass in the fridge. After 2 hours, the liquid is ready. You pour the liquid into and kind of place, or leave it in the glass. Then, you put a tiny little part in your finger of sodium acetate, and touch the liquid. It will then turn into dry ice.
