Acids and Bases
Properties of Acids:
Properties of ACIDS: 1. tastes sour
Properties of ACIDS: 1. tastes sour 2. reacts with metals
Properties of ACIDS: 1. tastes sour 2. reacts with metals 3. Turns blue litmus paper -- pink
Properties of ACIDS: 1. tastes sour 2. reacts with metals 3. Turns blue litmus paper -- pink 4. Produces hydrogen ions when mixed with water
Properties of Bases:
Properties of BASES: 1. tastes bitter
Properties of bases: 1. tastes bitter 2. Feels slippery
Properties of bases: 1. tastes bitter 2. Feels slippery 3. turns pink litmus paper blue
Properties of bases: 1. tastes bitter 2. Feels slippery 3. turns pink litmus paper blue 4. Produces hydroxide (OH - ) ions when mixed with water
Some people think that acids and bases are opposites.
indicator – substance which changes color when it touches an acid or a base
example: litmus paper
example: litmus paper pH paper
We need a way to tell if acids or bases are strong or.
pH scale: --tells the concentration of hydrogen ions in a substance
pH scale: --tells the concentration of hydrogen ions in a substance --tells how acidic or basic a substance is
pH scale: --goes from 0 to 14
pH scale: --goes from 0 to 14 --acids have pH = 0 - almost 7 --bases have pH = over 7 - 14
pH scale: --goes from 0 to 14 --acids have pH = 0 - almost 7 --bases have pH = over 7 – 14 --Water is and has a pH =.
Ch. 8. pH Scale Used to measure how acidic or basic a substance is Ranges from 0-14.
Chapter 9 Acids, Bases, and Salts
Chapter Nineteen: Solutions
PH. pH—Scale to measure how acidic or basic a solution is 0-14 Pure water is 7 and neutral (not an acid or base) Acids—less than 7(lower number more acidic)
Ch 11 Acids & Bases Test Review. 1.Color Change; Universal indicator- yellow, orange and red Blue Litmus paper turns red 2.) Sour taste and conducts.
Acids and Bases Properties of Acids 1. Taste. Acids and Bases Properties of Acids 1. Taste sour 2. Red litmus paper is.
825. Key concepts/skills: Level 1: Define key vocabulary. Level 2: Identify the basic properties of acids and bases and determine acid or base using litmus.
Properties of Acids & Bases By: Ms. Bowie. Acids are substances that: Taste sour!
Chemistry Notes: Acids and Bases
Acids, Bases, and Solutions
Chemistry Goal 10. Substances can be classified as acid, base, or neutral based on their pH. Acids and bases are solutions usually with water as.
Acids, Bases, and the pH scale. Acids Acids pH of 0 - < 7 pH of 0 - < 7 React with metals and Bases React with metals and Bases Tend to taste sour Tend.
The chemical of life. Acids Sour taste, leaves burning sensation Increase hydrogen ions (H+) in solution.
Acids and Bases Have Two Different Faces. Acids and Bases I I
CHAPTER 8 ACIDS & BASES. IDENTIFYING ACIDS A. IDENTIFYING ACIDS A. AN ACID IS A COMPOUND THAT PRODUCES HYDRONIUM IONS (H 3 O + ) WHEN DISSOLVED IN WATER.
TCAP Review Lesson 17 Vocabulary Foldable (IX)
ACIDS AND BASES. ACIDS & BASES Acids are substances that produce hydrogen ion in solution. (H + (aq) ) Bases are substances that produce hydroxide ions.
Chapter Nineteen: Solutions 19.1 Water 19.2 Solutions 19.3 Acids, Bases, and pH.
An acid is a substance that produces a hydronium ion (H 3 O + ) when placed in water. Examples of Acids:
