Transcript of Catalyst: Terminology Takedown 1. Ions 2. Reactants 3. Salts End.
Binder Organization Binder checks on each review day for each of
our unit test
You should have tabs labeled with the following (1) Learning Targets, (2) Notes, (3) In Class Work, (4) Homework, (5) Labs, Lab Repots, and Projects, and (6) Exit Slips, Quizzes, Tests
Everything you are given will now have a page number and this will help you keep your binder in the proper order.
Taste and Texture Test In the well plates at your table there are 8
different substances.
Play with each of the substances and categorize them based on what you see
Be ready to defend your groups reasons.
Today’s Learning Targets 6.1 – I can describe the common
properties of acids, bases, and salts. I can distinguish them based on taste, texture, ability to conduct electricity, and other observable properties.
Today’s Focus Question
What are the properties of the chemicals that we will be using to dispose of our dead body?
Today’s Agenda1. Catalyst
2. Taste Test
3. Acid/Base Properties Lecture
4. Categorize That Compound!
5. Acid/Base Classification Systems
6. Acid/Base Simulator
7. Work Time
8. Exit Slip
Acids and Bases We can categorize a number of
compounds as either acids or bases.
Acids react with bases to produce a salt in a neutralization reaction
Conducting Electricity
We say things can conduct electricity or not conduct electricity. REMEMBER – Metals are good conductors
When you dissolve an ionic compound in a solution it breaks apart into its ions.
This positive and negative charge allows for the solution to now conduct electricity.
HCl H+ + Cl-
Allow for it to conduct electricity!
Conducting Electricity
You need charges to conduct electricity. Therefore, in order to conduct electricity you need ions.
IONIC compounds conduct electricity and COVALENT
compounds do not!
Common Properties of Acids
Aqueous solution
Sour
Conduct an electrical current
React with a base to form a salt
Most contain hydrogen in its chemical structure (NOT REQUIRED)
Common Properties of Bases
Aqueous solution
Taste bitter Think about how it tastes when
soap gets in your mouth
Dilute bases feel slippery
React with an acid to produce a salt
Bases conduct an electrical current
Most contain OH- (NOT REQUIRED)
Common Properties of Salts
Ionic compound (contains an anion and cation)
Forms when an acid and base react in a neutralization reaction.
Characteristic salty taste
Conduct electricity
Categorize that Compound!
With your table you are going to create a mini-poster
Use this poster to help create a visual representation of acids, bases, and salts.
Make sure to incorporate properties such as taste, texture, ability to conduct electricity, and other observable properties.
USE PICTURES!
