(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. 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. 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. Chapter 8.1. Objectives. Describe the ionization of strong acids in water and the dissociation of strong bases in water.. Distinguish between solutions of weak acids or bases and solutions of strong acids or bases.. 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. 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. 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. Jennie L. Borders. Section 19.1 – Acid-Base Theories. Acids have a . sour. taste, change the color of an . indicator. , can be strong or weak . electrolytes. in aqueous solution, and react with . Unit 8: Acids & Bases PART 1: Acid/Base Theory & Properties I hereby define acids as compounds of oxygen and a nonmetal. (1777) In fact, I just named the newly discovered gas oxygen , which means “acid-former.” 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 .
