**Question:**An unknown solution has a pH of 7.1. Which of these chemicals is likely to increase the pH the most when added to the solution?**Options:**- ○ HF- ○ KOH- ○ NH₃- ○ HNO₃**Explanation:**This is a multiple-choice question focused on understanding how different chemicals affect the pH of a solution. The pH scale measures the acidity or alkalinity of a solution, with values below 7 indicating acidity, values above 7 indicating alkalinity, and a value of 7 indicating neutrality.**Chemical Reactions:**- HF (Hydrofluoric acid) is a weak acid, which would not increase the pH.- KOH (Potassium hydroxide) is a strong base, which would increase the pH significantly.- NH₃ (Ammonia) is a weak base and will increase the pH, but not as much as a strong base.- HNO₃ (Nitric acid) is a strong acid, which would decrease the pH. The correct answer is KOH since it is a strong base and will increase the pH the most.

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
