False! Acids place before 7 on the pH scale when bases place after 7

Question 7

What are things that you can look for to help you identify acids?

Answer 7

-look for an H on the left side of the formula
-check if it’s aqueous

Question 8

What is the process for naming acids?

use this key
-ide = hydro ic acid
-ate = ic acid
-ite = ous acid

-COOH endings (polyatomic ions)
-H will be at the ending of the formula rather than at the beginning
-Rule: ate ic acid

Question 10

What can help you identify a base?

Answer 10

The presence of OH- with a metal or an ammonium (NH4) ion usually indicates the substance is basic when in solution

Question 11

Explain Neutralization Reactions

Answer 11

when acids and bases react their acidic and basic properties disappear and they produce neutral products

Question 12

What is pH?

Answer 12

the pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such as a measure of the acidity or basicity of the solution

Question 13

what are indicators?

Answer 13

determine whether a substance is an acid or base
