My Period Chemistry Class With Coleman

Mr Coleman Class was the coolest class a student could ask for. On Lab days was the funniest because you learn how to make things scientist do it really makes you feel like you are a big scientist trying to find the cure for aids or something. the only problem i had with mr coleman was him always calling me out when the whole class is talking but besides that Mr. Coleman is a cool teacher. 

PH Scale

(1.) The pH scale measures up to 0 to 14

(2.) Acids are 0 to 6.9 on the pH scale 
       Bases are 7.1 to 14 on the pH scale

(3.) An example of an acid with a corresponding pH is orange juice on 2.
       An example of a base with a corresponding pH is wine 8.

(4.) Number 7 on the pH scale equals neutral (not an acid or base)
