Is sodium thiosulphate solution a primary standard?
No, sodium thiosulfate solution is not typically considered a primary standard. It is commonly used as a titrant in redox titrations rather than as a primary standard due to its susceptibility to oxidation by air. Primary standards are typically pure, stable compounds that can be used to standardize solutions.
Why anhydrous sodium carbonate is a primary standard?
Anhydrous sodium carbonate is a primary standard because it is stable, easily obtained in a pure form, and can be weighed accurately. It does not contain any water molecules, making it easier to measure and calculate the exact amount required for a reaction. It can be used to standardize solutions in titrations by reacting stoichiometrically with an acid.
Symbol for Sodium hydroxide?
The symbol for Sodium Hydroxide is NaoH
What is the name of the formula NaOH?
Sodium hydroxide.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.

What can do NaOH use as primary standard?
Sodium hydroxide easily absorb water and carbon dioxide.
Why sodium hydroxide is not a suitable regent to prepare a primary standard solution?
Sodium hydroxide is hygroscopic, meaning it easily absorbs moisture from the atmosphere, which can lead to inaccurate concentration measurements. It is also prone to reacting with carbon dioxide in the air, affecting its purity. Additionally, due to its strong caustic nature, it can be hazardous to handle during preparation of primary standard solutions.
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
How do you standardization 1N hcl?
To standardize 1N HCl (hydrochloric acid), you would typically use a primary standard base, such as sodium hydroxide (NaOH), of known concentration to titrate the HCl solution. By carefully titrating the HCl with the NaOH, you can determine the exact concentration of the HCl solution. This information can then be used to adjust the concentration of the HCl solution as needed to make it accurately 1N.
How do you standardize 0.5 m hcl?
To standardize 0.5 M HCl, you would typically titrate it using a primary standard solution such as sodium carbonate (Na2CO3). By titrating a known volume of the HCl with the sodium carbonate solution and using the mole ratio between the two, you can calculate the exact concentration of the HCl solution. This process ensures that the concentration of the 0.5 M HCl is accurate for future use in experiments.

Sodium hydroxide.
What chemicals are there in Sodium hydroxide?
sodium hydroxide is itself a chemical. It can disassociate into a sodium cation and a hydroxide anion
Is sodium hydroxide a metal?
No, sodium hydroxide is a compound.
What is the common primary standard used in the laboratory to standardize of NaOH and HCl?
Sodium Carbonate (Na2CO3) is most commonly used to standardise acids as it is non-hygroscopic (doesn't absorb water from the atmosphere).Oxalic Acid (HOOCCOOH or H2C2O4) used to standardise bases
