pH Scale Used to measure how acidic or basic a substance is Ranges from 0-14
Acids Have H + (hydrion) ions pH: 0-6.9 Properties Sour taste React with metals Turn indicator RED Ex: lemon juice, milk
Bases Have OH - (hydroxide) ions pH: 7.1-14 Properties Bitter taste Have a slippery feel (like when you get bleach or cleaners on your hands) Turns indicator BLUE Ex: bleach, antacid
Neutral pH: 7 Ex: PURE water (tap water, bottled water, etc. are not PURE because there are minerals added to them)
Buffers A weak base or acid used to NEUTRALIZE a strong acid or base Weak base neutralizes a strong acid Weak acid neutralizes a strong base Salts are produced when neutralization occurs Ex: HCl + NaOHNaCl + H 2 O Ex: using an antacid for heartburn Heartburn – caused by stomach acid (STRONG ACID) entering the esophagus Antacid – products like Tums and Rolaids (WEAK BASE)
