<u>Answer:</u> The substance that produces fewest particles is CH_2Cl_2

<u>Explanation:</u>

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

Covalent compounds do not dissociate into ions when dissolved in aqueous solution.

For the given options:

  • <u>Option 1:</u>  Sodium nitrate

The chemical formula of sodium nitrate is NaNO_3

The ionization reaction for the given compound follows:

NaNO_3(aq.)\rightarrow Na^+(aq.)+NO_3^-(aq.)

This produces in total of 2 ions.

  • <u>Option 2:</u>  CH_2Cl_2

The given compound is a covalent compound and do not dissociate into its ions. It remains as such as a single unit.

  • <u>Option 3:</u>  K_2SO_4

The chemical name for the given compound is potassium sulfate.

The ionization reaction for the given compound follows:

K_2SO_4(aq.)\rightarrow 2K^+(aq.)+SO_4^{2-}(aq.)

This produces in total of 3 ions.

  • <u>Option 4:</u>  Sodium phosphate

The chemical formula of sodium phosphate is Na_3PO_4

The ionization reaction for the given compound follows:

Na_3PO_4(aq.)\rightarrow 3Na^+(aq.)+PO_4^{3-}(aq.)

This produces in total of 4 ions.

Hence, the substance that produces fewest particles is CH_2Cl_2

Potassium hydroxide is classified as an arrhenius base because koh contains
mixas84 [53]

Answer: hydroxide ions

Explanation:

According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion  and a bases is a substance that ionizes in the water to give hydroxide ion .

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

As KOH can give hydroxide ions on dissociation , it is considered as arrhenius base.

KOH\rightarrow K^++OH^-
