An acidic solution is a type of solution that has an excess of hydrogen ions (H+), giving it a pH less than 7.
Think of an acidic solution like lemon juice. Just as lemon juice has a sour taste due to its acidity, an acidic solution also has more "sour" hydrogen ions.
Hydrogen Ion (H+): A positively charged ion formed of a hydrogen atom that has lost its electron.
pH Scale: A measure from 0 to 14 used to specify the acidity or basicity/alkalinity of an aqueous solution.
Acid: A substance that donates protons or hydrogen ions and/or accepts electrons.
