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. Science Lab Supplies, a chemistry lab instruments supplier, dispatches it from Ambala, India to schools, colleges, institutes, tender contractors and distributors.
Specifications
The kit is built around six named equilibrium systems covering buffer pairs, a weak base, a coloured complex ion, the chromate/dichromate interconversion and a sparingly soluble salt. It is written as a predict-then-test investigation, with worksheets for students 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.
- Common-ion effect and buffers with the acetate and benzoate pairs.
- Acid/base control of the yellow chromate and orange dichromate balance.
- 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?
Six: acetic acid/sodium acetate, benzoic acid/sodium benzoate, ammonium hydroxide, iron(III) thiocyanate, chromate/dichromate and silver acetate.
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?
Science Lab Supplies in Ambala, India supplies the kit and quotes it for colleges, schools and contractors, singly or alongside other chemistry lab equipment in India.
Is teacher support included?
Yes. A teachers manual accompanies the student worksheets and explains the predictions and expected observations for each system.
