What is the chemical name of Baking soda?

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

Baking soda is the common name for the chemical compound Sodium bicarbonate.
Its chemical formula is NaHCO3, indicating it is composed of one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms.
It is widely used as a leavening agent in baking, where it reacts with acidic components in batter to release carbon dioxide gas, causing the mixture to rise.

Option A: This is a different chemical compound (KHCO3). While it is also a bicarbonate, it contains potassium instead of sodium.
Option B: This compound is unstable as a solid and primarily exists in aqueous solutions, not as a powder for baking.
Option C: This is the chemical name for common table salt (NaCl), which is a seasoning and preservative.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Chemical nomenclature of common household substances as background academic context rather than a clinical decision trigger.
In a clinical setting, Sodium Bicarbonate is used as a systemic antacid to neutralize stomach acid and is administered intravenously to correct severe metabolic acidosis.
Nurses must monitor patients receiving IV Sodium Bicarbonate for signs of fluid overload, changes in urinary pH, and electrolyte imbalances, particularly hypokalemia (low potassium).
What if? If a patient has hypertension or heart failure, using baking soda (Sodium Bicarbonate) as a home remedy for indigestion is contraindicated due to its high sodium content, which can worsen fluid retention and blood pressure.

How to Approach the Question

This is a factual recall question that tests your knowledge of basic chemistry.
Identify the key term in the question: 'Baking soda'.
Recall or deduce the chemical name associated with this common substance.
Evaluate the options provided. 'Sodium bicarbonate' is the correct chemical name. The formula NaHCO3 confirms this.
Eliminate incorrect options by identifying what they are: Potassium bicarbonate is a different salt, Calcium bicarbonate is related to water hardness, and Sodium chloride is table salt.
