Sodium carbonate and sodium hydrogen carbonate are salts of sodium. The chemical formula of sodium hydrogen carbonate is NaHCO, it is a white solid crystal salt composed of sodium and bicarbonate ions. Citric acid (C6H8O7) is a tri-carboxylic acid (see structure below) and will require three equivalents of base to neutralize it. But when considering the chemical properties, the major difference between sodium carbonate and sodium hydrogen carbonate is the presence of hydrogen in the chemical structure of sodium hydrogen carbonate; sodium carbonate has no hydrogen atoms. Site Use Terms Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda (especially in North America and New Zealand) or bicarbonate of soda, is a chemical compound with the formula NaHCO3.

It is a crystalline compound that can readily undergo effloresce; then it forms the monohydrate form. Both sodium carbonate and sodium hydrogen carbonate are alkaline, salt compounds.But they differ in chemical and physical properties. Moreover, it is hygroscopic. Copyright © 2020 Andlearning.org It means this compound can absorb water vapor from the air when we expose it to normal air. Sodium Hydrogen Carbonate Structure The chemical structure is also given below where this ionic compound […] Sorry we cannot compare more than 4 products at a time. sodium hydrogen carbonate, 6 Reproduction of any materials from the site is strictly forbidden without permission. The other process for preparing NaHCO3 involves dissolving soda with water and allow to pass CO2 thought the solution. As for physical properties, the hygroscopic nature of sodium carbonate is the main difference. It has no melting or boiling point because it starts to convert into sodium carbonate at 50 °C. It is a salt composed of a sodium cation (Na ) and a bicarbonate anion (HCO3 ). Both sodium carbonate and sodium hydrogen carbonate are alkaline, salt compounds. Among these two compounds, sodium carbonate is a salt having the chemical formula Na2CO3. 1. It quickly reacts with acids to form salts or carbonic acid and decomposes further to give water and the CO2. Similarly, sodium hydrogen carbonate is a salt having the chemical formula NaHCO3. Summary. Pricing & availability is not currently available. It is not toxic, so health hazards are also limited when compared to other strong acids.
