Question

identify the product or products of the following acid - base reaction: 2hclo₄ + ba(oh)₂ →. 2h₂o + ba(clo₄)₂ h(oh)₂ + ba(clo₄)₂ 2h₃o⁺ + bacl₂ h₂o + baclo₄

Explanation:

Step1: Recall acid - base reaction rule

In an acid - base reaction, an acid ($HClO_4$) reacts with a base ($Ba(OH)_2$) to form a salt and water. The hydrogen ions ($H^+$) from the acid combine with the hydroxide ions ($OH^-$) from the base to form water, and the remaining ions form the salt.

Step2: Analyze ion combination

$HClO_4$ dissociates into $H^+$ and $ClO_4^-$, and $Ba(OH)_2$ dissociates into $Ba^{2 + }$ and $OH^-$. Two $H^+$ from $2HClO_4$ combine with two $OH^-$ from $Ba(OH)_2$ to form $2H_2O$, and $Ba^{2+}$ combines with two $ClO_4^-$ to form $Ba(ClO_4)_2$. The balanced reaction is $2HClO_4+Ba(OH)_2 = 2H_2O + Ba(ClO_4)_2$.

Answer:

$2H_2O + Ba(ClO_4)_2$ (corresponding to the first option)
