pH is a measure of the acidity or alkalinity of a solution. It's calculated as the negative logarithm (base 10) of the concentration of hydrogen ions in a solution.
Think about it like a seesaw. On one side, you have acids and on the other, bases. The pH scale is like the fulcrum that balances them out. A low pH means there are more acidic substances (like lemon juice), while a high pH indicates more basic substances (like baking soda).
Acid: A substance that donates protons or hydrogen ions and/or accepts electrons.
Base: A substance that can accept protons or donate a pair of valence electrons.
Neutralization Reaction: A chemical reaction in which an acid and base react quantitatively with each other to produce water and a salt.
