Ion present in all alkalis
WebAlkalis. Alkalis are bases that dissolve in water. Common alkali-containing substances are lyes, ammonia, hair-relaxing agents, nonphosphate detergents, dishwasher soaps, and disk batteries. Lyes are alkaline agents that contain sodium hydroxide (NaOH), potassium hydroxide (KOH), or calcium hydroxide (Ca (OH) 2 ). WebAlkalis produce hydroxide ions, OH- in aqueous solution. For example: NaOH (aq) → Na+(aq) + OH-(aq) Alkaline solutions have pH values greater than 7. Neutral solutions A …
