Answer explanation

anion is ion with negative charge

monoatomic anion is an anion made of only 1 element (Cl^-1, S^-2, O^-2, etc)

HCl --> hydrochloric acid

polyatomic anion is an anion made of

more than 1 element (NO₃^-, SO₄^-2, PO₄^-3, etc)i

H₂SO₄ --> Sulfuric acid (SO₄ is called sulfate, use ate-ic)

H₂SO₃ --> Sulfurous acid (SO₃ is called sulfite, use ite-ous)

What is the primary function of a buffer solution in a chemical reaction?

• To increase the reaction rate

• To act as a catalyst

• To maintain a constant pH

• To change the color of the solution

Answer explanation

Buffers mitigate changes in acidity and basicity

Which of the following properties is common to all acids?

• They turn red litmus paper blue

• They are all odorless
