Question

sodium bicarbonate is commonly known as baking soda. its added to many batters because it reacts during baking to produce gas bubbles, creating a light texture in the finished product. a spoonful of baking soda sodium bicarbonate is composed of sodium ions and bicarbonate ions (hco3 - ) bonded together. which formula correctly represents sodium bicarbonate? choose 1 answer: a nahco3 b na(hco3)2 c na2hco3

Explanation:

Step1: Determine ion charges

Sodium ion ($Na^+$) has a +1 charge and bicarbonate ion ($HCO_3^-$) has a - 1 charge.

Step2: Balance charges in compound

To form a neutral compound, the charges must balance. Since the charges of $Na^+$ and $HCO_3^-$ are equal in magnitude but opposite in sign, one sodium ion combines with one bicarbonate ion.

Answer:

A. $NaHCO_3$
