Acid Anything that increases the hydronium ion (H 3 O + ) concentration
Base Anything that increases the hydroxide ion (OH - ) concentration
Base Direct – OH- is contained in the base NaOH + H 2 O Na + + OH - + H 2 O Indirect – OH- is produced in the reaction NH 3 + H 2 O NH 4 + + OH -
Bronsted – Lowry Definition Acid – substance that can donate a proton HBr + H2O H3O+ + Br- Acid
Bronsted – Lowry Definition Base – substance that can accept a proton NH3 + H2O NH4+ + OH Base
Strong acid/Base Is completely converted to ions in water
Weak acid/Base Is partially converted to ions in water
Strong and Weak
Properties of Acids Turn Litmus indicator red Taste Sour Dissolve active metals React with bases to form a salt and water
Properties of Bases Turn Litmus indicator blue Taste bitter Feel Slippery React with acids to form a salt and water
Acids to know HCl Hydrochloric Acid H 2 SO 4 Sulfuric Acid HNO 3 Nitric Acid HC 2 H 3 O 2 Acetic Acid
Bases to know Alkali metal Hydroxides –LiOH Lithium Hydroxide –NaOHSodium Hydroxide –KOHPotassium Hydroxide NH3Ammonia
Neutralization Any time you react an acid with a base you get a salt and water HCl + NaOH NaCl + H2O Acid basesalt water HNO3 + LiOH LiNO3 + H2O

Acids and Bases Chapter 24. Acids… Definition: When an acid dissolves in water, H+ ions (charger particles) are formed H+
Chemistry 1010 Acids and Bases. Molarity The number of moles of solute in 1 liter of solution Molarity = Moles of Solute Liters of Solution.
Precipitation reaction – reaction in which an insoluble product forms Precipitate – an insoluble solid that separates from the solution Solubility – maximum.

Chapter 14: Acids and Bases and pH
Acids and Bases. Acids: Compounds that dissociate (give off) one or more hydrogen ions (H+) when dissolved in water (proton donors) Bases: Compounds that.
Acids & Bases Acids Arrhenius Model Produce hydrogen ions aqueous solution. HCl H + (aq) + Cl - (aq) Acids you SHOULD know: Acids you SHOULD know:
Ch. 14 Acids & Bases.
1 Some Properties of Acids þ Produce H + (as H 3 O + ) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule) þ Taste sour þ.
Aim: What are acids and bases?. Acids 1.Acids can be strong or weak electrolytes in aqueous solutions. 2.Acids (ex: HCl) react with certain metals to.
ACIDS AND BASES Sections 8.3 and 8.4. Acids A acid is a compound that produces hydronium (H 3 O + ) ions when dissolved in water. Examples: HCl – hydrochloric.
Acids & Bases. What are they? Acids & Bases An acid is any substance that releases H + ions in water.

Acids and alkalis Solutions can be sorted by whether they are: acid, alkali or neutral. When a substance dissolves in water it makes a solution.
COMMON SENSE IS LIKE DEODORANT, THE PEOPLE WHO NEED IT THE MOST NEVER USE IT.
