Explanation:
Detailed explanation-1: -Balanced chemical equation: 2 NaOH aq ⏟ Sodium hydroxide + H 2 SO 4 ( aq ) ⏟ Sulphuric acid → Na 2 SO 4 aq ⏟ Sodium sulphate + 2 H 2 O l ⏟ Water. Q.
Detailed explanation-2: -The reaction between sulfuric acid and sodium hydroxide is called neutralization, and the products are sodium sulfate and water only. The molecular equation is: H2SO4(aq)+2NaOH(aq)→Na2SO4(aq)+2H2O(l) H 2 S O 4 ( a q ) + 2 N a O H ( a q ) → N a 2 S O 4 ( a q ) + 2 H 2 O ( l ) .
Detailed explanation-3: -Complete answer: The reaction that takes place between an acid and a base to give out salt and water as the final products is known as a neutralization reaction.
