Have you been searching for environmentally friendly chemistry experiments to use in your high school laboratory? This stoichiometry experiment replaces a conventional aluminum to alum lab by using sodium carbonate and calcium chloride...

Is butter better? In terms of saturation, young chemists find out! Using titration methods, they will compare the degree of unsaturation of butter with that of margarine. Knowing the unsaturation, they can make conclusions about the...

Whether in the UK or in the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, just note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in...

Chemistry pupils titrate vitamin C with indophenol indicator. They determine the amount of vitamin C in a variety of fruit juices and conduct qualitative analysis. This is an outstanding instructional activity for high school chemists...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the lesson requires...

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general...

Keep it simple with this chemistry assignment. Learners examine an acid-base titration graph and answer four questions about the data. Then they will balance neutralization equations and calculate molarity for several specific solutions....

This 60-question comprehensive exam was designed to determine who would go on to compete in the 2000 US National Chemistry Olympiad. Hopefuls answer multiple choice questions regarding all chemistry topics taught in the first year...

Eight multi-step chemistry problems, including analyzing a titration, writing equations, predicting products and limiting reagents, calculating concentrations of ions, and using stoichiometry to solve for unknowns in reactions make up...

In this chemistry olympiad problem solving instructional activity, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.

The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Young chemists analyze Titration curves as part of this acids and bases learning exercise. Other problems include calculating concentrations, determining equilibrium constants, and a few multiple-choice questions. Since this resource...

Chemistry scholars analyze acid base reactions and perform concentration computations. This worksheet gives them an opportunity to work with acid base titrations from a variety of approaches. It would serve as a valuable homework exercise.

A useful introduction is given to recap Bronsted-Lowry acid base theory before multiple tables are completed. Pupils should be able to calculate the pH or concentration of certain solutions and also provide the definitions for some...

Titration curves are the focus of this chemistry video. Students see that if a weak base is titrated with a strong acid, then the pH equals the pKb at the half-equivalence point. The base will have an equilibrium, but the acid will not...

The College Board published the mean score on the 2016 AP Chemistry exam as a 2.69, but a minimum of a three is required to earn college credit. Help pupils study for the upcoming exam with actual test questions, sample answers, and...

2018 saw some of the highest AP Chemistry scores in years. The College Board released each test question covering topics from enthalpy to net ionic equations, as well as scoring guidelines and more to benefit future scientists. Example...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment document...

This is not your standard standardization lab! Take titration into the high-tech age with a simulated workbench. Learners perform titrations to standardize a sodium hydroxide solution using a KHP solution of unknown concentration....
