Does an alkali easily neutralize a concentrated acid or a dilute acid?
Alkalies can neutralize both concentrated and dilute acids, but dilute acids are 'more easily' neutralized (i.e. require a smaller amount of alkali for the same amount of acid). It is a simple chemical reaction, the amount of alkali required to neutralize an acid can be calculated if you know how they react and the strengths of the acid and alkali. E.g. if you use Potassium Hydroxide (KOH) to neutralize Hydrochloric acid (HCL) the reaction is: KOH + HCL --) KCL + H2O So one molecule of KOH neutralizes one molecule of HCL If you have 1 molar KOH, then : 10 ml of dilute HCL (0.1 molar strength) will be neutralized by 1 ml of KOH 10 ml of a strong HCL (10 molar strength) will be neutralized by 100 ml of KOH Hope that helps.
Why use ethanolic KOH?
ethanolic KOH can precipitate the impurities in solution
What is the Gibbs free energy of KOH?
Del G of KOH = -379.07 Kj/mol hope it is of some use
Why do you use KOH ethanol for the isolation of piperine and What are their uses?
I assume you mean ethanol + KOH? if so, in order to prevent co-precipitation of piperine and the resin acids, dilute ethanolic KOH is added to the concentrated extract to keep acidic materials in solution as their potassium salts (acid/base rxn occurs). basically it keeps impurities in solution, while piperine precipitates out.
How can you titrate with perchloric acid verses glacial acetic acd?
Since they are both acids, you don't usually titrate one against the other. If you want to titrate something, you should use one acid and one base. If one of them is a weak acid/base, the other should be a strong acid/base.So if you want to titrate a solution of acetic acid, use a solution of a known concentration of sodium hydroxide (NaOH) or potassium hydroxide (KOH) instead. You can also use either of those two strong bases to titrate a solution of perchloric acid.

What is the compound that reacts with potassium to form potassium hydroxide?
Potassium Hydroxide(KOH) is a base (it is "basic"). An acid will neutralize a base. Acetic acid can be used to neutralize KOH. Baking soda is a base, so it will not work to neutralize KOH.
Why do we use KOH in saponification reaction?
KOH is used to prepare liquid soaps.
Why use ethanolic KOH?
ethanolic KOH can precipitate the impurities in solution
Which catalyst can we use for ethoxylation?
KOH
Name the reagents used for absorbing CO2 CO O2 during flue gas analysis by ORSAT method?
we use ; KOH for absorbing CO2. 100 mg KOH and 200 ml purified water. Pyrogallic acid for absorbing O2 Cu2Cl2 with ammonium chloride for absorbing CO.
What is the Gibbs free energy of KOH?

Use of KOH in dermatologist office?
KOH (potassium hydroxide) is used to determine if a fungal infection exists on the skin.

What is the balanced equation for phosphoric acid and potassium hydroxide?
When solving this type of problem, first use the ion charges to predict the formulas of the products. Then use coefficients to balance the equation. H3PO4 (aq) + 3 KOH (aq) --> K3PO4 (aq) + 3 H2O (l)
