When sulfuric acid (H2SO4) reacts with sodium hydroxide (NaOH), which salt is formed?
A
K2SO3
B
Na2SO3
C
Na2SO4
D
K2SO4
Verified step by step guidance1
Identify the reactants: sulfuric acid (H\_2SO\_4) is a strong acid, and sodium hydroxide (NaOH) is a strong base.
Recognize that when an acid reacts with a base, a neutralization reaction occurs, producing a salt and water.
Determine the ions involved: sulfuric acid provides H\^+ and SO\_4\^{2-} ions, while sodium hydroxide provides Na\^+ and OH\^- ions.
Combine the ions to form the salt: the SO\_4\^{2-} ion pairs with Na\^+ ions. Since SO\_4\^{2-} has a charge of -2, two Na\^+ ions (each +1) are needed to balance the charge, forming Na\_2SO\_4.
Confirm that the salt formed is sodium sulfate (Na\_2SO\_4), not sodium sulfite (Na\_2SO\_3) or potassium salts (K\_2SO\_4 or K\_2SO\_3), because the base used is sodium hydroxide, not potassium hydroxide.
