Question

What is the ionic formula for sodium nitrate?

Answer 1

The ionic formula is to find the cation and write down the symbol and charge with anion and symbol charge and combine the two to get the formula.

Complete step by step answer:
Sodium Nitrate acts as a fertilizer,inorganic sodium salt and also inorganic nitrate salt.
$NaNO_3$
It is white crystalline solid,odourless and has a slight bitter taste.Sodium Nitrate is an inorganic of an alkali metal with the chemical formula $NaNO_3$. It is formed by Cation $Na^+$ and Anion $NO_3$.Sodium Nitrate is a white solid which is very soluble in water.The Salt is also known as Chile Saltpeter of Peru Saltpeter due to large deposits found in Atacama Desert in these countries)which distinguishes from ordinary saltpeter,potassium nitrate. Nitratine, Nitrate of soda niter are the mineral forms.The molar mass is 84.9947 g/mol.Its density is 2.26 g/ml and melting point is 308 degree Celsius.
It is stable solid at room temperature.If one heats it for a long time it can explode and release toxic fumes.It is a strong oxidizer and used as a food preservative and salt substitute.
The nitrate ion has a central nitrogen atom bonded to three oxygen atoms through one double bond and one single bond which resonate with each other.They are found as an impure nitrate rock or gravel.

Note: It is a white crystalline coloured solid namely trigonal and rhombohedral and has a sweet smell.It is highly soluble in ammonia.It is used as a meat stabiliser,for improvement of meat texture,development of flavour in cured meat,removing warmed over flavour,and as an antimicrobial.It dissociates completely in water into sodium and nitrate ions.It can cause skin and eye irritation and swallowing high concentrations of sodium nitrate which can cause gastrointestinal tract injury,abdominal pain,diarrhoea, and nausea.
