Understanding the pH Scale. Identify whether the solutions listed below are acids or bases. Write the color expected for each indicator (phenolphthalein, litmus dye) when immersed and indicate the pH range you would expect.
pH values can range from 0-14. Determine whether the brief statements below describe an acid, a base, or a neutral solution. On the blank in front of the statement, write acid, base, or neutral. You may need to review your notes. _____ 1. Blue litmus paper turns red. _____ 2. Red litmus paper doesn’t change color. _____ 3.

A pH scale, then, measures how basic or acidic a solution is. It stands for potential of hydrogen, meaning that it measures how many hydrogen ions are in a specific solution. The more hydrogen ions, the more acidic a solution.
This worksheet contains various questions to help your students learn (or review) basic concepts about Acids, Bases, and the pH Scale. This engaging worksheet is great for science class practice, a quick assessment tool, a quiz, a science station, a homework assignment, morning work, early finishers...
The pH scale, from 0 to 14, is a measure of the acidity or alkalinity of a solution, and can be measured using universal indicator or a pH probe. Students should be able to: describe the use of universal indicator or a wide range indicator to measure the approximate pH of a solution. 4.4.2.2 Neutralisation of acids and salt production
