This demonstration illustrates acid-base indicators and complex ions. Four colored solutions are prepared: pink, blue, deep red (iron(III) thiocyanate complex ion) and colorless. Mixing the three colored solutions result . . .

Since your students can use plastic depression plates to study a series of acid-base reactions, you do not need elaborate titration equipment for this kit. -- Designed for use by students who have a limited background in . . .

This practical, highly visual introduction to pH measurement is an excellent way to show students that science is something they do, not something that is done to them. -- Includes: 12 LAB-AID Chemplates w/spatula; 1 dro . . .

Materials for Seven Experiments -- In this lab students perform seven experiments which provide them with a thorough introduction to the characteristic properties of acids and bases. -- Includes: 12 LAB-AIDS Chemplates w . . .

Students carry out a series of dramatically colorful experiments which help them better understand pH and its relationship to acids, bases and their effect on indicator dyes. -- Includes: 12 Lab-Aids Chemplates; 2 drop c . . .

Students explore indicators and pH, and perform micro and quantitative titrations. -- They will also calibrate their own pH meter to use as a measuring device in the remainder of the module. -- Includes: microplates, mic . . .

Introduce students to the fundamentals of mixtures and solutions and more -- This kit includes four activities designed to introduce Biology students to the fundamentals of mixtures and solutions. Students learn to disti . . .

This fun and effective chemistry card game teaches students how to identify conjugate pairs, an important concept essential to an understanding of acids, acid protonization and dissociation. Developed by David Williams. . . .
