The pH scale! Ranges from 0-14 A PH in the middle of the scale - a ph of 7 is a neutral ph while a ph between 0-7 is considered acidic and 7-14 is considered basic. Now back to our hydrogen ion concentration from yesterday- A low pH- one that is acidic will have a higher concentration of hydrogen ions than a high ph - one that is basic To test your knowledge- I want you to solve for the hydrogen ion concentration of a ph of 3 vs a Ph of 9 to see the difference using the formula I gave you yesterday Drop your answers in the comments! #Science #scicomm #biochemistry #stem - @dr.lizberry
