What type of chemical adds H+ to a solution?Multiple choice question.acidneutralbasealkaline

Break Down the Problem

1. Identify the characteristics of each option: acid, neutral, base, alkaline.
2. Determine which of these options is known to add $\text{H}^+$ ions to a solution.

Relevant Concepts

• Acids: Substances that can donate $\text{H}^+$ ions (protons) to a solution.
• Neutral: A solution neither adds nor removes $\text{H}^+$ ions; it maintains a pH of 7.
• Bases: Substances that accept $\text{H}^+$ ions or release $\text{OH}^-$ ions in a solution.
• Alkaline: Often synonymous with basic; refers to a solution that is basic.

Analysis and Detail

1. Acids are defined specifically by their ability to increase the concentration of hydrogen ions ($\text{H}^+$) in a solution.
2. The term "neutral" refers to a pH of 7, where there is an equal concentration of $\text{H}^+$ and $\text{OH}^-$ ions.
3. Bases and alkaline substances reduce the concentration of $\text{H}^+$ ions in a solution, either by accepting them or by increasing the concentration of $\text{OH}^-$ ions.

Verify and Summarize

The only category from the options that directly adds $\text{H}^+$ ions to a solution is an acid.

Final Answer

Acid is the correct answer as it adds $\text{H}^+$ ions to a solution.
