Question

adding water to a solution increases the solutions concentration.
true
false
an arrhenius base produces hydronium ions when dissolved in water.
true
false
the ph scale measures
the level of saltiness of a solution
concentration of oh−(aq) ions
concentration of acids
concentration of h+(aq) ions
neutralization involves mixing acids and salts together.
true
false

Explanation:

1. For the first statement: Adding water (dilution) reduces the amount of solute per unit volume, lowering concentration.
2. For the second statement: Arrhenius bases produce hydroxide ions ($OH^-$), not hydronium ions ($H_3O^+$), in water.
3. For the third question: The pH scale is defined based on the hydrogen ion ($H^+(aq)$) concentration in a solution.
4. For the fourth statement: Neutralization is the reaction between an acid and a base, not an acid and a salt.

Answer:

1. False
2. False
3. concentration of H+(aq) ions
4. False
