Question

What do hydrogen ions (H+) and hydroxide ions (OH–) come together to form?

a titrant

an acid

a base

water

Which of the following is a strong acid?

HCl

OH–

NaOH

NaCl

Answer 1

Hydrogen ions and hydroxide ions come together to form the substance of water. As H^+ + (OH^-) = H2O. A particularly strong acid, as it dissociates into its ions quickly and to a full extent would be HCl. It would have 100% dissociation, as the compound fully ionizes to form hydrogen and chlorine ions in the solution.

Answer 2

• When hydrogen ions (H⁺) and hydroxide ions (OH⁻) come together, they form water. The correct option is the last option - water

• The strong acid among the given options is HCl. The correct option is the first option - HCl

Product of reaction

From the question, we are to determine the product formed when H⁺ and OH⁻ come together

When, hydrogen ions (H⁺) and hydroxide ions (OH⁻) come together, they neutralize each other to form water (H₂O) as shown in the equation below.

H⁺ + OH⁻ ↔ H₂O

Hence, when hydrogen ions (H⁺) and hydroxide ions (OH⁻) come together, they form water. The correct option is the last option - water

From the second question, we are to determine which of the given option is a strong acid

A strong acid is one that is completely dissociated or ionized in an aqueous solution. They have a high capacity to lose a proton (H⁺).

Among the given options, HCl is the only strong acid, and it has a high capacity to lose its proton.

Hence, the strong acid among the given options is HCl. The correct option is the first option - HCl
