Properties of Acids and Bases Experiment
In this activity, students observe various acid and base reactions. They observe the effect of acids and bases on the chemical indicators litmus and phenolphthalein. They also observe that not all metals react equally with acids and not all acids, even those with the same concentration, react equally with metals. Students also collect and identify the gas produced when an acid reacts with a carbonate and perform a simple titration to determine the concentration of an unknown solution.

Kit #320Simulating Threshold Effects of Soil pH on Hydrangea PlantsIn this simulation activity, students model how hydrangea plants are affected by soil pH. Agricultural lime (mostly CaCO3) is often used to adjust soil pH. Soil pH is a factor that influences the color of hydrangea flowers and the health of the plant. Below a positive threshold pH, hydrangea flowers are blue, above this...

Kit #83Identification of Substances
In this kit, students are asked to identify common metallic and non-metallic ions in zinc, cadmium, antimony, barium, sulfate, sulfide, sulfite, and carbonate. Through the identification process, students learn that each substance has distinctive properties. As a closing activity, students conduct chemical tests on four unknown substances. All test results are safe, clear, colorful,...

Kit #85Chemical Formulas
With this activity, students learn to predict the formula of a compound by comparing the amount of the compound produced when combining different ratios of reactant solutions. Students use a chemical analysis method to determine the ratio of each of the ions in the product substance’s composition. Knowing the ratio, students can...

Kit #84Identification of Chemical Reactions
A very important outcome of studying science is to acquire the ability to make and interpret observations. Students initially observe and describe seven different solutions. They then combine pairs of these chemical solutions and use their observations to determine whether or not a chemical reaction took place. Finally, they test an unknown solution and...

Kit #81RpH Indicator
In this very popular Applied Science Concept Kit, students perform a series of very colorful tests that help them to develop a better understanding of pH, and its relationship to acids and bases, and its effect on indicator dyes. Using a LAB-AIDS® Chemplates® and universal indicator, each student creates his own pH...

Kit #181Antacid Study
In this lab activity, students compare several “over-the- counter” brands of antacid tablets for solubility and the ability to neutralize acid. Your stomach contains gastric juices used for digestion. Gastric juices contain hydrochloric acid (HCl) and typically have a pH of 2-3. Antacids are medicinesthat contain alkaline compounds (bases) that neutralize excess...

Kit #180Aspirin Study
Aspirin (acetylsalicylic acid) is probably the most used and abused non-prescription drug. Using aspirin tablets brought from home, students analyze and compare them with the Brand "X" aspirin included in this Lab-Aid. They determine the percentage of aspirin and "filler" components in a tablet, check pH and calculate the per aspirin cost. Students draw...
