17. A solution that contains more OH -ions than than hydrogen ions is

A solution that contains more OH⁻ ions than hydrogen ions (H⁺) is known as a basic or alkaline solution. In this type of solution, the pH level is greater than 7, indicating that it has a higher concentration of hydroxide ions compared to protons. Common examples include baking soda dissolved in water or soap solutions, which can create a slippery feel! This concept is easy to observe in everyday life! For instance, consider how antacids work—they are basic and help neutralize excess stomach acid (which has more H⁺ ions). So, when you pop one of those tablets, you're balancing out the acidity to ease that stomach discomfort!
