Question

question ① given the formula for borate as bo₃³⁻, what is the formula for boric acid? answer h₄bo₄ h₃bo₃ hbo₄ h₂bo₂ i dont know yet

Explanation:

Step1: Recall acid - anion relationship

An acid is formed by adding hydrogen ions ($H^+$) to the anion. The borate ion is $BO_3^{3 - }$.

Step2: Balance the charge

To neutralize the 3 - negative charge of $BO_3^{3 - }$, we need 3 hydrogen ions ($H^+$). So the formula of boric acid is $H_3BO_3$.

Answer:

$H_3BO_3$ (corresponding to the option $H_3BO_3$ in the multiple - choice list)
