🌊 Strong bases completely dissociate in water, forming a high concentration of hydroxide ions ($OH^−$).
    🧪 Common examples include Group 1 hydroxides (e.g., $NaOH$, $KOH$) and some Group 2 hydroxides (e.g., $Ca(OH)_2$, $Ba(OH)_2$).
    ⚗️ In titrations, strong bases are used to neutralize acids, allowing for the determination of the unknown concentration of the acid.
     📈 The equivalence point in a strong acid-strong base titration occurs at pH 7.
     📝 The general equation for neutralization is: $Acid + Base \rightarrow Salt + Water$.
     💡 Strong bases are also used in various industrial processes such as soap making and paper production.
