PPT-Conjugate acids and bases

Different definitions of acids and bases Acids are proton donors Brønsted Lowry definition they generate H 3 O in water Arrhenius definition Bases are proton acceptors they generate OH. Acids turn blue litmus to red 2 Acids turn methyl orange to red Bases effect indicators 1 Bases turn red litmus to blue 2 Bases turn methy l orange to yellow 3 Bases turn phenolphthalein to purple Acids neutralize bases producing a salt and water Ba Sodium hydroxide.

Some Important Acids. (All acids have H atoms). Properties of Acids. Sour Taste. Reacts with Metals (Produce Hydrogen Gas). Reacts with Carbonates (Produce CO2). Turn Litmus Paper Red. Natural Indicators. Different definitions of acids and bases. Acids are proton donors (. Brønsted. Lowry definition). they generate H. 3. O. +. in water (Arrhenius definition). Bases are proton acceptors. they generate OH. Definitions of acids and bases;. Bronsted’s conjugate acid-base pairs concept;. Determination of [H. 3. O. . ], [OH. -. ], and pH for strong acids and strong bases;. Determination of [H. 3. O. . ], [OH. Acids are all around us.. Foods like lemons, limes, and oranges contain acidic compounds.. When wine is oxidized, it becomes acetic acid.. Our muscles produce lactic acid.. Our stomach uses hydrochloric acid to break down food.. Chemistry. Jacqueline P. Hancock, B.S., . M.Ed. Acid-Base Theories. Bracken Cave, near San Antonio, Texas, is home to twenty to forty million bats. Visitors to the cave must protect themselves from the dangerous levels of ammonia in the cave. Ammonia is a byproduct of the bats’ urine. You will learn why ammonia is considered a base.. 10.1. Acids and Bases. 2. Acids. Arrhenius acids . produce H. . ions in water. H. 2. O. . H. Cl(. g. ) . H. . (. aq. ) Cl. . (. aq. ). are electrolytes. have a sour taste . Explain the chemical composition of acids and bases, and explain the change of pH in neutralization reactions.. D12. I can differentiate between acids and bases.. Learning Target. When dissolved in water, they ionize (form ions). Naming Basic Acids. When identifying and naming acids, you are looking for two characteristics:. The compound/molecule will begin with hydrogen, H-. The number of following atoms will then determine the two ways of naming. Review!. What is an electrolyte?. What are examples? . Aim # 1 How do we define acids and bases?. Acidity:. . measure . of the hydrogen (H. +. ), hydronium (H. 3. O. +. )ion concentration of a . solution. Dissolve in solution to produce ions. . Acid Base Equations. General Form of Dissociation.

Your body has water in it so they are always dangerous to living things.. Bases are just as dangerous as acids.. In low . concentrations. Objectives. Relate the process of ionization to the formation of acids and bases. Explain qualities of acids and bases . Compare the acidity of substances, using the pH scale and pH indicators . Use molarity and titration to determine the concentration of an acid .
