Why is nano3 soluble in water?
When an ionic compound dissolves in water, the solution contains ions rather than neutral particles. A polyatomic ion does not break up into separate atoms in solution. Thus, a solution of sodium nitrate, NaNO3, contains sodium ions and nitrate ions; no nitrogen ions or oxygen ions are present.
Why are hydrocarbons insoluble in water?
The family of compounds known as the hydrocarbons contain only carbon and hydrogen. Because the difference between the electronegativities of carbon and hydrogen is small (EN = 0.40), hydrocarbons are nonpolar. As a result, they do not dissolve in polar solvents such as water.
Is nano3 completely soluble in water?
Sodium nitrate is a white deliquescent solid very soluble in water….Sodium nitrate.

Is NaNO3 more soluble than NaCl?
The solubility of the salts at constant total sodium molality always followed the relative order NaNO3 > NaNO2 > NaCl > NaOH for the four background electrolytes studied here.
Why are most hydrocarbons hydrophobic?
Hydrocarbons are hydrophobic because: A. the covalent bonds between hydrogen and carbon are nonpolar. the hydrogen bonds between hydrogen and carbon are nonpolar.
Is NaNO3 a polar compound?
No, sodium nitrate is NOT polar. Sodium nitrate is an ionic substance due to the fact that sodium completely loses an electron to the nitrate ion to…
Why is NaNO3 a solid?
In its pure standard form, sodium nitrate (NaNO3 N a N O 3 ) is present as a crystalline solid. Take note that the solubility of NaNO3 N a N O 3 increases with temperature which is a characteristic of most solid substances. Since it is made of a cation and an anion, NaNO3 N a N O 3 is an ionic compound.
Is NaNO3 ionic or covalent?
The Na has a +1 charge and the NO3 has a -1 charge, therefore the “bond” that holds them together is an ionic bond.
Is NaNO3 soluble or insoluble in water?
On the solubility table we can see that NaNO3 (Sodium nitrate ) is soluble in water. Because it is soluble in water, we would expect that it would dissociate into its ions. We could also just get some NaNO3 and see if it dissolves in water, that would also tell us if it is soluble or insoluble.
Why are hydrocarbons not soluble in water?
Home Science Chemistry Atoms & Molecules. Why Are Hydrocarbons Not Soluble in Water? Hydrocarbons do not dissolve in water because they are nonpolar compounds and water is a polar solvent. The general solubility rule is “like dissolves like,” meaning polar solvents dissolve polar solutes and nonpolar solvents dissolve nonpolar solutes.
What happens when you mix NaNO3 and Ag2SO4?
2 AgNO3 + Na2SO4 –> 2 NaNO3 + Ag2SO4 NaNO3 is highly soluble in water; 1800g/L, whereas Ag2SO4 is not; solubility in water is 0.12g/L. This leads to a precipitate of Ag2SO4 in a solution of water. How do you make 10ppm of NaNO3?
What causes NaNO3 to dissociate in water?
The unequal sharing of electrons in NaNO3 causes it to dissociate in water to form Na(+) and NO3(-). Hydrocarbons (more equal amount of sharing of electrons) are non polar and if mixed with water they form a separate layer due to their different densities.
