Acids and Bases Chapter 24
Acids… Definition: When an acid dissolves in water, H+ ions (charger particles) are formed H+
Acids… H + ions join with H 2 O to form hydronium compounds H 3 O +
Acids… Properties of Acids: 1) tastes sour
Acids… Properties of Acids: 2) Corrosive- can eat away at metals
Acids… Properties of Acids: 3) Can make special compounds called INDICATORS change color. Litmus paper turns RED
Acids… Properties of Acids: 4) Can burn skin
Acids… Examples: Citric acid in fruit Lactic acid in milk Acetic Acid in Vinegar Stomach Acid Battery acid….
Acids… Dissociating (Breaking Up) in Water: HCl + H 2 O H 3 O + + Cl-
Acids… Strength Strong acids are substances that completely dissociates in water to form as many H+ ions as possible
BASES… Definition: Forms OH- (hydroxide) in water and accepts H+ ions to make water –OH-
BASES… Properties of Bases: 1) tastes bitter
BASES… Properties of Bases: 2) NOT corrosive 3) Also reacts with indicators, LITMUS paper turns BLUE
BASES… Properties of Bases: 4) Can burn skin
BASES… Properties of Bases: 5) Feels slippery
BASES… Examples: Bleach, ammonia Borax Eggs Salt Water Some medicines like milk of magnesia Some other soaps
BASES… Dissociating (Breaking Up) in Water: NaOH + H 2 O Na + (aq) + OH- (aq) Aq = in water (Aqueous)
BASES… Strength: Completely dissociates in OH- ions
Fit these Examples into the Acid/Base categories Tomatoes HNO 3 Magnesium oxide Mg(OH) 2 Oranges HCl Car battery NaOH Antacid Bleach Ammonia (NH 3 ) Italian Salad Dressing
General Properties Indicators Neutralization Reactions
Intro to Acids & Bases General Properties Indicators Neutralization Reactions.
Acids, Bases, and pH Part 2. Properties of Acids Acids: –Taste Sour (never use taste to test the presence of an acid) –Are Electrolytes –Are Corrosive.
Acids and Bases 1.
Acid Anything that increases the hydronium ion (H 3 O + ) concentration.
Precipitation reaction – reaction in which an insoluble product forms Precipitate – an insoluble solid that separates from the solution Solubility – maximum.
Unit: Chemical Interactions Chapter 8: Solutions When substances dissolve to form solutions, the properties of the mixture change. 8.1: A solution is a.
Standard 5.a- Students know the observable properties of acids, bases, and salt solutions. 2/22/12.
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.
Chapter 14: Acids and Bases and pH
pH, Acidic and Basic Solutions
Chapter 25 Lesson 1.
Acids and Bases. Acid- a substance that produces hydrogen ions (H + ) in a water solution. Taste sour Corrosive.
Chapter 23 Acids, Bases, and Salts
LEQ: What techniques in the lab setting will be used to identify acids and bases?
Ch Acids & Bases I. Intro to Acids & Bases (p ) Definitions Properties Uses.
Unit 18 Acids and Bases. I. Defining Acids & Bases A. Properties Acids Bases 1. Taste sour bitter (not in lab) ex: Citrus ex: soap fruits, yogurt vinegar.
Acids and Bases SC Physical Science Standard PS-3.8 Classify various solutions as acids or bases according to their physical properties, chemical properties.
ACIDS, BASES, & SALTS ACIDS Contain hydrogen ions, H + also called hydronium ions, H 3 O + Taste sour (remember not to taste chemicals as a rule) Dangerous.
Acids and Bases 8 th gr. Chemistry. Acids Forms hydronium ions H 3 O+ when reacting with water Sour taste Corrosive Conducts electricity Can.
