Sodium hydroxide can be used for the base-driven hydrolysis of esters (also called saponification), amides and alkyl halides. [16] However, the limited solubility of sodium hydroxide in organic solvents means that the more soluble potassium hydroxide (KOH) is often preferred. Touching a sodium hydroxide solution with bare hands, while not ...
A strong base is one that is fully dissociated in aqueous solution. For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be written as H + + OH − → H 2 O
Bases with only one ionizable hydroxide (OH −) ion per formula unit are called monoprotic since they can accept one proton (H +). Bases with more than one OH- per formula unit are polyprotic. [16] The number of ionizable hydroxide (OH −) ions present in one formula unit of a base is also called the acidity of the base.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).

Sodium hydroxide (NaOH) is an Arrhenius base because it dissociates the hydroxide ion when it is dissolved in water. [3] Aqueous solutions may contain, especially in the alkaline zone or subjected to radiolysis, hydrated atomic hydrogen and hydrated electrons. [citation needed]
NaOH + HCl → NaCl + H 2 O. The salt NaCl is then said to consist of the acid rest Cl − and the base rest Na +. The removal of electrons to form the cation is endothermic, raising the system's overall energy. There may also be energy changes associated with breaking of existing bonds or the addition of more than one electron to form anions.
Those colored shapes are called “printer’s color blocks” or “process control patches,” and they’re there to help the printing team who prints the food packaging.
