0.1 M NaOH SDS: Understanding the Safety Data Sheet for Sodium Hydroxide
Introduction
Sodium hydroxide (NaOH), also known as lye or caustic soda, is a strong alkaline substance widely used in various industries, including soap making, paper manufacturing, and water treatment. When handling NaOH, it's essential to understand its safety data sheet (SDS) to ensure safe handling, storage, and use. In this article, we'll delve into the SDS of 0.1 M NaOH, a commonly used concentration of sodium hydroxide.
SDS Overview
A safety data sheet (SDS) is a document that provides information on the safe handling, use, storage, and emergency procedures for a hazardous substance. The SDS for 0.1 M NaOH is divided into 16 sections, each providing critical information on the substance.
Hazards Identification
Hazard Classification: 0.1 M NaOH is classified as a corrosive substance, posing a risk to human health and the environment.
