  • NaOH and KOH both are strong alkalis the difference is in their solubilities in organic solvents and organic reactions for example alkyl halides undergo substitution in aq. NaOH but elimination in alcoholic KOH'''

  • KOH (like NaOH) is hygroscopic. Even at high temperatures, solid KOH does not dehydrate readily.

  • Approximately 121 g of KOH will dissolve in 100 mL of water at room temperature (compared with 100 g of NaOH in the same volume).

  • KOH, like NaOH, serves as a source of OH−, a highly nucleophilic anion that attacks polar bonds in both inorganic and organic materials.While KOH and NaOH are both strong bases, potassium is further down on the Periodic Table than sodium. That gives you valuable information regarding the nature of these elements. A general rule of thumb is that atoms are more reactive going down a column, and are more reactive as you go toward the left of a row.

  • The pKb value of potassium hydroxide is 0.5, while the value for sodium hydroxide is 0.2 (the smaller the value of pKb, the stronger the base). Therefore, NaOH is stronger than KOH. In addition, sodium is less electronegative than potassium, so NaOH is more willing to release the hydroxy group and it is stronger base.

  • Their first ionization energies are different as well: 496kJ/mol for sodium, 419kJ/mol for potassium. The relatively small excess of hydroxide- released by KOH compared with NaOH doesn't seem like it would impart that much added reactivity.

  • In industrial scale, KOH is more expensive than NaOH (depends on concentration of KOH), so NaOH is widely used instead of KOH. But they both shows many similarities.

  • NaOH creates the solids and KOH creates liquid soap.

What is the difference between NaOH s and NaOH aq?

NaOH (s) refers to solid sodium hydroxide, which is in a solid state. NaOH (aq) refers to sodium hydroxide dissolved in water, resulting in an aqueous solution. The (s) and (aq) notations distinguish between the physical states of the substance.


What is the reaction equation between NaOH and Potassium Hydrogentartrate or KHT?

The reaction equation between NaOH and potassium hydrogen tartrate (KHT) is: 2KHT + 2NaOH → 2KNaTartrate + 2H2O


Balanced equation of HCH3COO NaOH?

The balanced equation for the reaction between acetic acid (HC2H3O2) and sodium hydroxide (NaOH) is: HC2H3O2 + NaOH → NaC2H3O2 + H2O


Why is NaOH heated before adding BaCl2?

Heating NaOH before adding BaCl2 helps to dissolve NaOH completely in water, ensuring that no solid NaOH remains undissolved in the solution. This is important because the reaction between BaCl2 and NaOH requires the NaOH to be in solution to react with the BaCl2. Heating the solution can also speed up the reaction between NaOH and BaCl2.

Is 8mM NaOH equivalent to 0.1M NaOH?

No, these are totally different concentrations! The ratio of difference is a multiplication factor of 12.5 smaller or bigger respectively.So: 8mM = 8 millimolar = 0.008 molar = 0.008Mand 0.1M = 0.1 molar = 100 millimolar = 100mM


What is the difference between NaCl and NaOH in terms of their chemical properties and uses?

Sodium chloride (NaCl) is a salt commonly used for seasoning and preserving food, while sodium hydroxide (NaOH) is a strong base used in manufacturing processes like soap making and cleaning products. NaCl is a neutral compound, while NaOH is highly alkaline. NaCl is soluble in water, while NaOH is highly soluble and corrosive.


What is the safest way to tell the difference between vinegar and sodium hydroxide?

The safest way to tell the difference between vinegar and sodium hydroxide(NaOH) is litmus paper test as vinegar is acidic while NaOH is basic in nature. So vinegar will turn blue litmus paper to red and NaOH will turn red litmus paper to blue. We can also check vinegar by tasting because it contains acetic acid which is a weak acid and would taste sour. But sodium hydroxide is a very strong base and may cause severe burns if not handled with care. Do not attempt to taste NaOH as it will cause severe health problems.


Is the reaction between NaOH and water Chemical?

No. It is a physical process, so it technically isn't a reaction.
