Acid and Base Notes. I can distinguish between an acid and a base.. I can list the characteristics of an acid and a base.. I can name acids.. I can name bases.. What do you think an acid is?. Give an example of an acid.. 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. p. 191-195. Anything about the pH scale?. Alkaline is another name for a base.. acid/base intro video. What can you tell me about acids and bases?. 1.2 Acids and Bases. pH scale- . indicates the acidity of a solution. What is an Acid?. A solution with an excess of H. +1. ions. How do we know that a chemical is an acid?. Most Acids start with an ‘H’ in their chemical formula. What are the properties of an Acid?. MEASUREMENT. REACTIONS. The sour and spicy tastes are properties of acidic substances. The bitter taste is a . property of basic . substances. ACIDS & BASES. INTRODUCTION. Your own body produces acids and strong bases. 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.. . Acids and their properties. An acid is any compound that increases the number of . hydronium . ions. . Hydronium forms when and H separates from an acid and bonds with water = H. 3. O. . Acids have a . 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. #.
