What is Strong Base?
A base that completely dissociates in aqueous solution to give OH⁻ ions. Examples include NaOH, KOH, Ca(OH)₂, and Ba(OH)₂. Strong bases react completely with strong acids in neutralization. Their conjugate acids are very weak acids.
Properties & Characteristics
A strong base is one that completely dissociates in water to produce hydroxide ions. Common examples include NaOH, KOH, Ca(OH)₂, and Ba(OH)₂. The hydroxide ion concentration equals the initial base concentration. Strong bases have very high pKb values (or equivalently, pKa for the conjugate acid close to 14 or above).
Uses & Applications
Strong bases are used in soap manufacture (saponification), paper production (kraft process), and industrial cleaning. Sodium hydroxide is used to produce various chemicals and in the food industry. Strong bases are used in analytical titrations.
Safety Information
Strong bases are highly corrosive, causing severe chemical burns particularly dangerous to eyes. Sodium and potassium hydroxide solutions can cause deep tissue damage. Appropriate protective equipment must be worn when handling strong bases.
Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
