Are your students struggling with calculation pH from hydronium or hydroxide concentrations? This color map is super helpful. My students are able to make their calculations quickly and accurately using it. I use this in my pre-AP chemistry class.
Have them note what they know – pH, pOH, hydronium or hydroxide concentration and then see where they need to go from there. The arrows give the formula to use to get the answer. Print it in color, 2 to a page for students to have as a reference or to scaffold work until they can do it on their own. If color ink is an issue, print a class set and laminate them.
I have included a practice assignment with answers for students, and a quiz with a key as well.
