Acids and Bases List as many things that you can about acids or - PowerPoint PPT Presentation

Acids and Bases • List as many things that you can about acids or bases in 15 seconds. • Share with table mates.

List brainstorm

Acids • All acid formulas start with hydrogen • Look for the pattern on the next slide

Patterns? • HCl • Hydrochloric acid • H 2 SO 4 • Sulfuric acid • HNO 3 • Nitric acid • HF • Hydrofluoric acid • H 3 PO 4 • Phosphoric acid

Science Definitions • Acids: – Link to vid – Hydronium • Bases: • pH • 1 x 10 -1 1 x 10 -4 vs

Characteristics Acids Bases Taste--- Taste--- Metals--- Metals--- Tissues--- Tissues---

Concentration • Percent: • Parts — per • Molarity:

Concentration 2 Calculate the molarity of sodium carbonate in a solution that contains 38.6 g Na 2 CO 3 in 0.5 L of solution.

Concentration 3 What volume of 0.86 M table sugar (C 12 H 22 O 11 ) has 50 g of sugar in it?

Concentration 4 How many grams of H 2 SO 4 are in 5 mL of 3.2 M acid solution?

Dilution Concentrated = Diluted (Vol)(Conc) = (Vol)(Conc) How much 0.1 M HCl can be made from 20 mL of 2 M HCl ?
