Take out a calculator!!

WRITE THIS STUFF DOWN!!!

Copy the whole thing later, take screenshots, jot stuff down right now... I DON'T CARE JUST PLEASE SAVE THIS STUFF SOMEWHERE FOR TOMORROWS QUIZ PLEASE

This quizziz is already posted on google classroom! Please use it!!!

Multiple Choice

acid

base

Multiple Choice

Donates protons (H⁺)

acid

base

I'M GONNA ASK YOU ABOUT THESE AGAIN LATER

Open Ended

What is an electrolyte?

Type response here

ELECTROLYTE

A substance that is able to conduct electricity when dissolved in water (aqueous solution)

Multiple Choice

__________ are electrolytes

only acids

only bases

both acids and bases

neither acids nor bases

ACIDS AND BASES ARE ELECTROLYTES

BECAUSE THEY PRODUCE IONS WHEN DISSOLVED IN WATER

(H⁺ and OH^- ions)

Multiple Choice

NH₃ + H₂O ↔ NH₄⁺ + OH^-

^{Which compound is the ACID?}

NH₃

H₂O

NH₄⁺

OH^-

Multiple Choice

NH₃ + H₂O ↔ NH₄⁺ + OH^-

^{Which compound is the CONJUGATE BASE?}

NH₃

H₂O

NH₄⁺

OH^-
