ACIDS, BASES, and SALTS

What is an ACID? By the Arrhenius definition, an acid is a compound that – when dissolved in water -dissociates and produces _______________________ ion(s) and anion(s)

Acids taste ________________

For this year, you can identify a compound as an acid if the formula begins with __________________. Write HCl as dissociated

Concentrated acids are dangerous! http://www.youtube.com/watch?v=98V1fqaQHsA

What is an BASE? By the Arrhenius definition, a base is a compound that – when dissolved in water - dissociates and produces _______________________ ion(s) and cation(s)

Bases taste ______________ and feel ______________

Arrhenius bases can be identified as ionic compounds that contain _________________________. Write NaOH as dissociated.

Some other compounds are bases by the Bronsted-Lowry definition of bases. This definition is that a base is a ________________________ acceptor. The only one of these you need to know is

Strong bases are dangerous!

What happens when you mix an acid and a base together What happens when you mix an acid and a base together? __ HCl + __ NaOH → __ + __

What general type of reaction is this? This is also called an

The products of an acid + a base are ___________________ and a salt The products of an acid + a base are ___________________ and a salt. A salt is defined as a _____________ from a base + an ____________ from an acid. Most _______________ compounds are salts.

Review: In order to be conductive, a substance must have____________ particles that can _____________. What is an electrolyte?

Are solutions of acids and bases electrolytes? Why or why not?

A chemical dye that changes its color under different conditions is an ____________________. For example: Litmus is ________ in acid, & ________ in base.

The acid-base indicators we’ll be using this year are PHENOLPHTHALEIN and UNIVERSAL INDICATOR

How strong an acid or base is – is measured by its.

A pH of 7 is _____________ A pH of 7 is _____________ H+ ____ OH1- A pH of less than 7 is _____________ H+ ____ OH1- A pH of greater than 7 is ____________ H+ ____ OH1-
