Characteristics of acids and bases Chem

last ahh unit

What color does the lithmus paper turn for ACIDS

Blue paper turns red

How do ACIDS taste

Sour taste

What is their reactivity

React with metals to form H₂

How can you easily tell if a compound is an ACID

it has an H in the front of it

How can you tell if a counpound is easily a BASE

If it contains a METAL and an OH^-

How do BASES taste

They have a Bitter taste and are Slippery to touch

What color does the Lithmus paper turn for BASES

Red paper turns Blue

pH above 7

Bases

pH below 7

Acids

Which conducts electricity

Both do

Which one dissolves oils and fats

Bases (think about the soap)

Which one turns Phenolphtalein pink

BASES (think about the lab where you add the long tube containing OH to make it pink)

Which one turns Phenolphthalein clear

ACIDS

When reacting with Metals which produces Hydrogen Gas

ACIDS

What increases when an ACID is dissolved in a solvent according to ARRHENIUS

the concentration of hydrogen ions (H+)

What increases when a BASE is dissolved in a solvent according to ARRHENIUS

the concentration of hydroxide ions (OH-)

Which one is considered a Proton Donor

An ACID

Which one is considered a Proton Acceptor

A BASE

T or F A solution that contains electrolytes conducts electricity

True because electrolytes are substances that dissociate into ions in solution, allowing the solution to conduct electrical current.

Does a Strong of Weak Acid transfer H+ to water to form H3O

Strong Acid

Does a Strong or Weak Acid react with water only partially to form H3O ions

Weak Acid

What is the K value for a Weak Acid

<1

What is the K value for a Strong Acid

>1
