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. 

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....
