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?

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

Summarize

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.
