HON CHEMISTRY: So what makes lemons and oranges taste sour? 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.

After the lecture today, you’ll begin the simLAB: Acid & Base Solutions – HONORS. Open the lab here on the website. The link to the sim lab is on the lab sheets. You will type your observations and answers directly into the lab sheets. At the end of the lab, save your document as a PDF and submit it to BOTH your shared folder and TurnItIn.
