A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely. <span>The molarity of the sodium hydroxide solution cannot be determined accurately because s</span>olid sodium hydroxide is highly hygroscopic (absorbs water from the air) and cannot be accurately weighed. Sodium hydroxide form sodium carbonate because it absorbs carbon dioxide from the air.

Answer:

- To set the actual or exact concentration of sodium hydroxide.

- It is hygroscopic.

Explanation:

Hello,

Standardization is a procedure in experimental chemistry to know the actual concentration of a solution, in this case, sodium hydroxide. Such process is carried out by titrating the solution of sodium hydroxide with acid potassium phthalate.

On the other hand, the molarity of sodium hydroxide is not determined accurately since it is a highly hygroscopic material, it means that it includes the water in its structure, therefore the determined molarity will not be accurate since there will be an amount of water included into the sodium hydroxide's exact amount.

Best regards.

polet [3.4K]
I remember coming across this question and the options were:
KOH, HCN, NH₃, HI, Sr(OH)₂

Now, a substance with a low pH is one that dissociates completely in water to release hydrogen ions, while basic substances dissociate completely to release hydroxide ions. Therefore, in the order of increasing pH:
HI, HCN, NH₃, Sr(OH)₂, KOH
