PPT-Acids & Bases And the Indicators that tell the story

Acids amp Bases are Based on WATER Depending on the amount of H or OH ions the water becomes either acidic or basic aka alkaline The pH scale determines the strength of the acidbase. 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 Chemistry . Acids and Bases. Properties and pH. Chemical Warfare!. What is an Acid?. 3 Major Definitions: Arrhenius, Bronsted-Lowry, and Lewis.. Arrhenius and Bronsted-Lowry say an acid is:. A proton donor. . The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution. Citric acid, acetic acid, and tartaric acid are shown here.. 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. Day 3. Naming Acids. Acids usually have H as the cation. . H. Cl. Acids are named depending on whether they are oxyacids (ternary acids) or non-oxyacids (binary acids). AP Chemistry, Mr. Guerrero. Acids. :. Sour taste. Turn litmus . red. Electrolytes- form ions in water. Corrosive-cause chemical burns to skin. React w/ metals to produce salt and H. 2. gas. . HX M . Taste. Acids taste sour. Foods. citrus fruits . yogurt and sour milk. carbonated beverages. vinegar. Acid. citric acid. lactic acid. carbonic acid. acetic acid. Bases taste bitter. Like soap. Touch. 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.. 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). A special solution. Acids and bases are ALWAYS in a water solution.. Your body has water in it so they are always dangerous to living things.. Bases are just as dangerous as acids.. In low . concentrations. Three Kinds of Mixtures. 1. A . solution. is an evenly-mixed mixture where you can. ’. t see its different parts. Solutions have the same properties throughout.. They can be in solid, liquid or gas form. Acids and bases are solutions. . An introduction to the properties of acids, bases, and the pH scale. Complete the following table. Element. Atomic. #. Mass #. Protons. Electrons. Neutrons. Ion, Isotope, or Neutral?. 82. 209. 16. 18. 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. 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 .
