Acid - โโโ A substance that produces H+ ions in a solution (proton donor) Base - โโโ A substance that produces OH- (hydroxide ions) in a solution pH - โโโ Measure of acidity of a solution Acidic - โโโ pH less than 7 Neutral - โโโ pH of 7 Alkaline (base) - โโโ pH above 7 Each number on the pH scale is - โโโ 10 fold pH equation - โโโ pH = - log[H+] Strong acid - โโโ The acid completely disassociates in water Strong base - โโโ A base that completely ionizes in a solution Acid goes with its - โโโ Conjugate base Base goes with its - โโโ Conjugate acid HCl (hydrochloric acid) - โโโ Strong acid HBr (hydrobromic acid) - โโโ Strong acid HI (hydroiodic acid) - โโโ Strong acid HNO3 (nitric acid) - โโโ Strong acid
H2SO4 (sulfuric acid) - โโโ Strong acid HCIO3 (chloric acid) - โโโ Strong acid HCIO4 (perchloric acid) - โโโ Strong acid LiOH (lithium hydroxide) - โโโ Strong base NaOH - โโโ Strong base KOH (potassium hydroxide) - โโโ Strong base RbOH (rubidium hydroxide) - โโโ Strong base CsOH (cesium hydroxide) - โโโ Strong base Mg(OH)2 (magnesium hydroxide) - โโโ Strong base Ca(OH)2 (calcium hydroxide) - โโโ Strong base Sr(OH)2 (strontium hydroxide) - โโโ Strong base Ba(OH)2 (barium hydroxide) - โโโ Strong base Weak acid - โโโ The acid does not completely dissociate in water Weak base - โโโ A base that does not completely ionized in a solution Buffers - โโโ A solution that can resist pH change when an acid or base is added. It maintains a stable pH by neutralizing the acid or base and absorbs excess H+ or OH- Buffers are combination of - โโโ Weak acid and its conjugate base or weak base and its conjugate acid Neutralization reactions - โโโ A reaction when an acid and base are mixed together to produce water and salt Neutralization of a strong acid, and a strong base result in what pH? - โโโ pH 7 Litmus paper - โโโ Used to test if a solution is acidic or basic If the litmus paper turns blue it is - โโโ Basic
