Why is potassium nitrate classified as aj electrolyte?

<span>KNO3 is a strong electrolyte because it completely dissociates into ions in water. Dissociates means it immediately breaks into ions of K+ (potassium cation) and NO3- (nitrate anion). Thus it also conducts electricity very well compared to a weak electrolyte.</span>

Potassium Nitrate is classified as an electrolyte because of its highly conductive nature when dissolved in water.

Explanation

Potassium nitrate represented as KNO3 are ionic bonded compounds.

They are polar substances as the electronegative difference between nitrate and potassium is very high, so they can easily break their bond and dissolve in water easily.

It has large range of applications. It is even used as gun powder, in firecrackers etc,.

As the KNO3 is easily soluble in water and they can form K+ and NO3- ions when dissolved in water.

These ions acts as conducting agents in the water solution so they act as electrolyte.

As electrolytes are the solutions which have the capacity to conduct electrical energy in the electrochemical reactions, the conductive nature of potassium nitrate dissolved in water makes them useful as an electrolyte in salt bridge experiment.

Two samples of the same compound are compared. what does the data represent? sample 1: 24.22 g carbon and 32.00 g oxygen sample

goblinko [34]

According to law of definite proportion:

In a compound, elements are always arranged in fixed ratio by mass.

Here, sample 1 has 23.22 g Carbon and 32.00 g Oxygen.

Converting mass into number of moles:

Molar mass of carbon is 12 g/mol and that of oxygen is 16 g/mol thus,

$n_{C}=\frac{m_{C}}{M_{C}}=\frac{24.22 g}{12 g/mol}\approx 2 mol$

Similarly, number of moles of oxygen will be:

$n_{O}=\frac{m_{O}}{M_{O}}=\frac{32 g}{16 g/mol}=2 mol$

The ratio of number of moles of carbon and oxygen will be:

$C:O=n_{C}:n_{O}=2:2=1:1$

Therefore, formula of compound will be CO.

Sample 2:

It has 36.22 g Carbon and 48.00 g Oxygen.

Converting mass into number of moles:

Molar mass of carbon is 12 g/mol and that of oxygen is 16 g/mol thus,

$n_{C}=\frac{m_{C}}{M_{C}}=\frac{36.22 g}{12 g/mol}\approx 3 mol$

Similarly, number of moles of oxygen will be:

$n_{O}=\frac{m_{O}}{M_{O}}=\frac{48 g}{16 g/mol}=3 mol$

The ratio of number of moles of carbon and oxygen will be:

$C:O=n_{C}:n_{O}=3:3=1:1$

The formula of compound will be CO.

Therefore, it is proved that carbon and oxygen are present in fixed ratios in both the samples.

Given the equation representing a system at equilibrium:

polet [3.4K]

I think the one that cause the equilibrium to shift would be :
3. adding a noble gas
Adding the noble gas will add more concentration to the KNO3, which will create different amount of equilibrium

hope this helps
