PPT-Acids and Bases Unit 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 Tastes sour Turns blue litmus paper red. 1. What are . acids. and how do they taste like?. What . acids. or . acidic . solutions. do you know?. What are . acids. and how do they taste like?. Taste: . sour, tart, tangy. What are . bases. . 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. 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.. Definition: . An acid is a substance that produces H. . ions in solution. Properties of acids. Tastes sour. Corrosive: . eats . away at other materials. Causes burns and tissue . damage. Able to conduct electricity. 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. Acids and Bases. Arrhenius definition. Bronsted-Lowry definition. pH. Strong vs weak acids. Neutralization reactions. Some Properties of Acids. Produce H. . (as H. 3. O. . ) ions in water (the hydronium ion is a hydrogen ion attached to a water molecule). 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. . 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 .
