Are nitrate ions always soluble?
So, nitrate is a really big anion, with a single charge. The lesser concentration of negative charge results in relatively lesser lattice enthalpies. Also, the possibility of the creation of hydrogen bonds with water enhances solubility by increasing enthalpy of hydration. That’s why almost all of nitrates are soluble.
Why is nitrate always soluble in water?
Explanation: Because the nitrate is not charge dense, the species in solution is less polarizing (as the nitrate ion, NO−3 ), and causes less solvent order upon dissolution. For this reason, many nitrate salts have solubility in non-aqueous solvents.
Are most nitrates soluble or insoluble?
Solubility Rules
- Alkali metal (Group IA) compounds are soluble.
- Ammonium (NH4+) compounds are soluble.
- Nitrates (NO3-), chlorates (ClO3-), and perchlorates (ClO4-) are soluble.
- Most hydroxides (OH-) are insoluble.
- Most chlorides (Cl-), bromides (Br-) or iodides (I-) are soluble.
Is no3 always soluble?
Salts containing nitrate ion (NO3-) are generally soluble. Salts containing Cl -, Br -, or I – are generally soluble.
What is insoluble with nitrate?
Water
Nitrate/Soluble in
Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
What ions are soluble?
Salts containing Group I elements are soluble (Li+, Na+, K+, Cs+, Rb+).
Are all chlorides soluble?
Chloride/Soluble in
What nitrates are not soluble?
Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
Which nitrates are not soluble?
Is nitrate a polyatomic ion?
For example, NO3− is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge….Polyatomic Ions.
| Name | Formula |
|---|---|
| nitrate ion | NO3− |
| nitrite ion | NO2− |
| permanganate ion | MnO4− |
| phosphate ion | PO43− |
Are all phosphates soluble?
h) All phosphates are insoluble except those of sodium, potassium and ammonium. Some hydrogen phosphates, such as Ca(H2PO4)2, are soluble.

Generally speaking, all nitrate salts are soluble in water just like sodium salts. But there are always exceptions. Although I am not pretty sure about this fact, but the following are insoluble in water despite being a nitrate/sodium salt. Bismuth oxynitrate.
What is the solubility rule for nitrates and acetates?
The Solubility Rules 1. The nitrates, chlorates, and acetates of all metals are soluble in water . Silver acetate is sparingly soluble. 2. All sodium, potassium, and ammonium salts are soluble in water. 3. The chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in water.
What are nitrate salts?
Nitrates are salts or esters of nitric acid, HNO 3, formed by replacing the hydrogen with a metal (e.g., sodium or potassium) or a radical (e.g., ammonium or ethyl). Some important inorganic nitrates are potassium nitrate (KNO 3), sodium nitrate (NaNO 3), silver nitrate (AgNO 3), and ammonium nitrate (NH 4NO 3).
