identify the substances that are likely to dissociate in water. check all that apply. sodium bromide (nabr) potassium hydroxide (koh) magnesium chloride (mgcl2) silicon dioxide (sio2) sodium oxide (na2o)

Answer

Answer:

  • sodium bromide (NaBr)
  • potassium hydroxide (KOH)
  • magnesium chloride (MgCl₂)
  • sodium oxide (Na₂O)

Explanation:

Step1: Define ionic compounds

Ionic compounds dissociate in water.

Step2: Analyze NaBr

NaBr is an ionic compound. It dissociates into Na⁺ and Br⁻ in water.

Step3: Analyze KOH

KOH is an ionic compound. It dissociates into K⁺ and OH⁻ in water.

Step4: Analyze MgCl₂

MgCl₂ is an ionic compound. It dissociates into Mg²⁺ and 2Cl⁻ in water.

Step5: Analyze SiO₂

SiO₂ is a covalent - network solid and does not dissociate in water.

Step6: Analyze Na₂O

Na₂O reacts with water to form NaOH. NaOH then dissociates into Na⁺ and OH⁻ in water. So effectively, Na₂O leads to dissociation in water through its reaction product.
