CHEMISTRY: So what do you think would cause these beautiful colors? Great intro to the properties of acids and bases, indicators and pH! Don’t forget The Physics Classroom assignment. If you need help on the last two levels, click on the Help Me button. It will give you the pH chart that matches certain indicator colors. Here’s a hint – Phenolphthalein indicator is always hot pink/magenta in a base.
And last hint – the more negative the H3O+ concentration (that means the higher the negative exponent) the more of a base that it is. The lower the number of the exponent (which actually makes it a higher number) the more of an acid it is.
How’s the exam review packet coming along? Help session for the exam Friday morning, 7:15ish A.M.
