Equilibrium Shifts Kit
Product Code : LSK-CL-10064
Equilibrium Shifts Kit (SKU LSK-CL-10064) lets students explore how chemical equilibria respond to change in six systems: acetic acid/sodium acetate, benzoic acid/sodium benzoate, ammonium hydroxide, iron(III) thiocyanate, chromate/dichromate and silver acetate. Students predict each result from theory, then test the prediction at the bench. The kit suits senior secondary and first-year college chemistry. It reaches schools, colleges, institutes, tender contractors and distributors through Science Lab Supplies, a chemistry lab instruments supplier based in Ambala, India.
Specifications
All six equilibrium systems of the kit, plus its method and documentation, are listed row by row below. In short, it covers buffer pairs, a weak base, a coloured complex ion, the chromate/dichromate interconversion and a sparingly soluble salt, written as a predict-then-test investigation with student worksheets and a teachers manual.

Applications and Experiments for the Equilibrium Shifts Kit
The equilibrium shifts kit turns Le Chatelier's principle and ionic equilibrium into visible colour and solubility changes. Students add a common ion, change acidity or dilute a mixture and watch the position of equilibrium move, which fits the Equilibrium unit of NCERT Class 11 chemistry and B.Sc. physical chemistry.
- Class 11 chemistry: effect of concentration changes on the iron(III) thiocyanate equilibrium, with small volumes added from Graduated Pipettes 2ml.
- Common-ion effect and buffers with the acetate and benzoate pairs, compared side by side in Test Piece tubes.
- Acid/base control of the yellow chromate and orange dichromate balance, adding acid or base dropwise from Calibrated Plastic Droppers.
- Solubility equilibrium of silver acetate.
Chromate and dichromate compounds are toxic and carcinogenic, ammonium hydroxide is corrosive with irritating fumes, and silver salts stain skin. Use gloves and goggles, work under supervision in a ventilated room, and dispose of chromium and silver waste as your safety rules require. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Standard Scope of Supply

Frequently Asked Questions
Which equilibrium systems are in the kit?
There are six: acetic acid/sodium acetate, benzoic acid/sodium benzoate, ammonium hydroxide, iron(III) thiocyanate, chromate/dichromate and silver acetate, each explored by predicting and then testing a shift.
Does it include hazardous chemicals?
Yes. The chromate/dichromate system involves toxic, carcinogenic chromium(VI) compounds, and ammonium hydroxide is corrosive. Use gloves, goggles, ventilation and supervision, and collect waste separately.
Who supplies the Equilibrium Shifts Kit?
Quotations for this kit come from Science Lab Supplies in Ambala, India. Colleges, schools and contractors can order it singly or together with other chemistry lab equipment in India from the same range.
Is teacher support included?
Yes. A teachers manual is included with the student worksheets. It supports the predict-then-test method, in which students forecast each equilibrium shift from chemical theory and then check it experimentally across the six systems.
