Sodium bicarbonate is a chemical compound widely used in household baking, fire extinguishers, and antacids. Which of the following chemical formulas correctly represents sodium bicarbonate?

  1. NaHCO3\text{NaHCO}_3Cevap
  2. B
    Na2CO3⋅10H2O\text{Na}_2\text{CO}_3 \cdot 10\text{H}_2\text{O}
  3. C
    NaOH\text{NaOH}
  4. D
    CaOCl2\text{CaOCl}_2

Cevap

The chemical formula representing sodium bicarbonate (baking soda) is NaHCO3\text{NaHCO}_3.
The chemical formula NaHCO3\text{NaHCO}_3 represents sodium bicarbonate (also called sodium hydrogen carbonate), commonly known as baking soda.

Adım Adım Çözüm

1
Identify the chemical name and constituent ions
Sodium bicarbonate is composed of sodium ions (Na+\text{Na}^+) and hydrogen carbonate/bicarbonate ions (HCO3−\text{HCO}_3^-).
Chemical names directly correspond to the constituent cations and anions.
2
Combine the ions to write the neutral chemical formula
Combining Na+\text{Na}^+ and HCO3−\text{HCO}_3^- gives NaHCO3\text{NaHCO}_3.
The charges +1+1 and −1-1 balance directly in a 1:1 ratio.
