Question

compound important species present when dissolved in water type of compound (check all that apply) ionic molecular strong acid weak acid strong base weak base hc₂h₃o₂ h₃o⁺, c₂h₃o₂⁻, hc₂h₃o₂, h₂o hf h₃o⁺, f⁻, hf, h₂o hbro₄ h₃o⁺, bro₄⁻, h₂o nabro₄ na⁺, bro₄⁻, h₂o

Explanation:

Step1: Identify molecular compounds

Molecular compounds are made of non - metals. All the given compounds are composed of non - metals. So, $HC_2H_3O_2$, $HF$, $HBrO_4$ and $NaBrO_4$ are molecular.

Step2: Identify acids

Acids donate $H^+$ in water. $HC_2H_3O_2$ and $HF$ are weak acids as they only partially dissociate in water (as indicated by the presence of the undissociated acid molecules in solution). $HBrO_4$ is a strong acid as it completely dissociates in water (no undissociated $HBrO_4$ molecules are present).

Step3: Identify ionic compounds

Ionic compounds dissociate into ions in water. $NaBrO_4$ is an ionic compound as it dissociates into $Na^+$ and $BrO_4^-$ ions in water.

Answer:

compound	ionic	molecular	strong acid	weak acid	strong base	weak base
$HF$		$\checkmark$		$\checkmark$
$HBrO_4$		$\checkmark$	$\checkmark$
$NaBrO_4$	$\checkmark$
