Calcium Hydroxide

Product Code : SCL-LC-12294

The Calcium Hydroxide Lab Chemical is an inorganic alkaline reagent used for supervised chemistry experiments involving limewater preparation, carbon dioxide testing, calcium salt chemistry, neutralisation, and qualitative inorganic analysis. It is suitable for schools, colleges, chemistry laboratories, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Calcium Hydroxide from Science Lab Supplies is intended for controlled educational and laboratory use where a calcium hydroxide reagent is required. The exact grade, assay, pack size, physical form, batch number, shelf life, SDS, COA, and regulatory documents must be confirmed before final quotation or publication.

Calcium hydroxide is commonly represented as Ca(OH)₂. It is also known as slaked lime, hydrated lime, calcium hydrate, and caustic lime. In teaching laboratories, it supports lessons on alkaline solutions, carbon dioxide detection, calcium compounds, neutralisation reactions, and practical chemical handling where the syllabus, SOP, and SDS permit.

Key Features

• Inorganic alkali reagent: suitable for supervised chemistry teaching and approved laboratory practical work.
• Formula reference: calcium hydroxide is represented as Ca(OH)₂.
• Limewater preparation support: used in approved procedures for preparing calcium hydroxide solution for carbon dioxide testing.
• Carbon dioxide demonstration value: supports classroom observations involving calcium carbonate formation from limewater.
• Calcium salt chemistry: useful for lessons on bases, hydroxides, solubility, and calcium compounds.
• Corrosive handling control: requires PPE, eye protection, dust control, and trained supervision.
• Documentation-led procurement: SDS, COA, assay, batch number, grade, and shelf-life details should be verified before use.

How to Use the Calcium Hydroxide

1. Read the current SDS, product label, and institutional risk assessment before use.
2. Confirm grade, assay, physical form, and pack size before issuing it for practical work.
3. Wear suitable PPE, including lab coat, gloves, and eye or face protection.
4. Use only the quantity required by the approved laboratory procedure.
5. Measure the reagent with a clean, dry spatula or compatible weighing tool.
6. Prepare limewater or other approved solutions only in labelled glassware or approved containers.
7. Avoid creating airborne dust during transfer, weighing, or mixing.
8. Dispose of residues according to institutional alkali and chemical-waste procedures.

Safety note: Use Calcium Hydroxide only in supervised laboratory procedures. Do not inhale dust, ingest, touch with bare hands, mix with strong acids carelessly, discharge to drains, or issue for unsupervised student handling.

Care & Maintenance

• Store tightly closed in a cool, dry, ventilated chemical-storage area.
• Protect from moisture, carbon dioxide exposure, strong acids, food items, and unlabelled containers.
• Use clean, dry tools and avoid returning unused or contaminated material to the original pack.
• Maintain SDS, COA, batch number, grade, assay, pack size, and shelf-life records for audit control.

Frequently Asked Questions

What is Calcium Hydroxide used for in a laboratory?

Calcium Hydroxide is used as an alkaline reagent for supervised limewater preparation, carbon dioxide testing, neutralisation demonstrations, calcium compound lessons, and qualitative chemistry work.

What is the formula of Calcium Hydroxide?

The formula of Calcium Hydroxide is Ca(OH)₂. Its CAS number is 1305-62-0 and its molecular weight is approximately 74.1 g/mol.

Is Calcium Hydroxide the same as slaked lime?

Yes. Calcium hydroxide is commonly called slaked lime, hydrated lime, calcium hydrate, or caustic lime. The final label should still be checked for grade, assay, and intended laboratory use.

Is Calcium Hydroxide hazardous?

It requires SDS-based handling because dust and alkaline contact can irritate or damage eyes, skin, and the respiratory tract. PPE, dust control, and trained supervision are required.

Is it suitable for school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when trained staff control dispensing, solution preparation, storage, and disposal.

Can Calcium Hydroxide be used for food or medical purposes?

No. This listing is for laboratory-use Calcium Hydroxide only. It should not be marketed or used as a food additive, medicine, dental product, agricultural input, cosmetic ingredient, or consumer product.
