pH and Solutions Lab
Acids, bases, pH and titration, with every beaker drawn to scale.
pH and Solutions Lab walks through acids and bases from first properties to titration. It starts with what acids and bases do and how to recognize them in formulas, then places everyday substances on the pH scale and shows how indicators such as litmus, phenolphthalein and universal indicator change color.
Then the numbers come in. Students find pH from hydrogen ion concentration, use pH plus pOH equals 14, tell strong from weak acids, understand a buffer and work through neutralization and titration. Strips, test tubes, beakers and burettes are drawn from the same numbers as the question.
What children practice
- Describe the properties of acids and bases and spot them in formulas
- Place common substances on the pH scale
- Predict indicator colors for litmus, phenolphthalein and universal indicator
- Find pH and pOH from concentration, and the reverse
- Compare strong and weak acids and say what a buffer does
- Write neutralization products, name the salt and do titration arithmetic
Levels
- Level 1: Properties of acids and bases
- Level 2: Acids, bases and formulas
- Level 3: The pH scale
- Level 4: Indicators
- Level 5: pH and concentration
- Level 6: Strong, weak and buffers
- Level 7: Neutralization and titration
- Level 8: Course mix
How it works
- Eight levels go from properties to titration, and Level 8 is a course mix.
- The game assumes 25 degrees Celsius, so pH plus pOH is always 14, and taste or touch is never used as a test.
- Your child needs five right answers and a finished practice timer to open the next level.
- Concentrations appear as powers of ten or decimals in moles per liter, and typed answers show the unit in the box.
Best for: A good fit for grades 9 to 12 in a chemistry course, when pH is first met as a number and students need to link it with what is happening in the solution.
Tip for parents: Test a few household liquids with red cabbage juice or a store-bought indicator strip, using adult supervision, and ask your child to predict acid or base before each test.
Questions parents ask
Does it cover logarithms of concentration?
It keeps the numbers clean. Level 5 uses concentrations that are powers of ten, so pH can be found without a calculator.
How is titration taught?
Level 7 draws a burette and a flask and asks for volumes and concentrations in neutralization, using M1 V1 equals M2 V2 for one-to-one cases. Sulfuric acid is treated as giving two hydrogen ions.
What do students learn about buffers?
Level 6 teaches buffers as a recall idea: what a buffer does when a little acid or base is added. It does not ask for buffer calculations.
