is sodium erythorbate ionic or covalent

Covalent and Ionic Bonds

I think that your teacher gave you a bad question and a bad answer If the question had asked whether all the bonds in sodium nitrate are ionic then it would be a different story However it is true that the bonds between the nitrogen and oxygen are covalent Nevertheless stating that sodium nitrate is ionic shouldn't be wrong

Ionic compound

In chemistry an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding The compound is neutral overall but consists of positively charged ions called cations and negatively charged ions called anions These can be simple ions such as the sodium (Na +) and chloride (Cl −) in sodium chloride or polyatomic species such as the

Sodium erythorbate

Sodium erythorbate (C 6 H 7 NaO 6) is a food additive used predominantly in meats poultry and soft drinks Chemically it is the sodium salt of erythorbic acid When used in processed meat such as hot dogs and beef sticks it increases the rate at which nitrite reduces to nitric oxide thus facilitating a faster cure and retaining the pink coloring As an antioxidant structurally related to

What is the formula of sodium phosphate?

Answer: Na3PO4 Explanation: This is so since sodium is in group 1 so has a valency of 1+ while phosphate is a polyatomic ion of valency 3− and thus we need 3 sodium atoms for each 1 phosphate ion hence Na3PO4 Overall nett charge of molecule mu

Is Sodium Nitrate Covalent or Ionic? Please explain why

28/05/2015Usually most of the compounds Sodium make are ionic So sodium nitrate is ionic too Covalent bonds are formed by sharing electrons between the bonded atoms In sodium nitrate ( Na+ and NO3- ) the bond is formed due to their electrostatic attraction which is caused by their charges 0 0 0 Login to reply the answers Post Anonymous 5 years ago It's ionic It contains the cation=Na+ and
