Can the saturated calomel reference electrode be used in strong alkaline media such as 2-5 N KOH solution?
No, Use a Mercury Oxide electrode in alkalai Media. Strong NaOH will damage glass. Available from Koslow Scientific Co.
Why the pH meter is always kept in saturated KOH solution?
KCl is a salt having Ph 7, it is highly ionizable.yet a small leakage of ions from the reference electrode is needed, forming a conducting bridge to the glass electrode. A pH meter must thus not be used in moving liquids of low conductivity. Sushant kumar
What volume of a 3m koh solution can be prepared by diluting 0.5 l of a 5m koh solution?
What volume(L) of 3M KOH solution can be perpared by diluting 0.5 L of %M KOH solution?
Why use ethanolic KOH?
ethanolic KOH can precipitate the impurities in solution
How to prepare 0.1 KOH solution?
Take 5.7g of KOH and dissolve in 1dm of water

Why alcohol is required in koh solution?
because KOH is hygroscopic
How do you make a 1 percent aqueous solution of potassium hydroxide?
1% solution of KOH contains 1g of KOH in 100g of solution. This means that you need to mix 1g of KOH and 99g of water.
What is the molarity of a solution when 50.0ml of a 4.00M KOH solution is diluted to 200ml. what is the percent concentration of KOH in this final solution. asume the density of 1.0gmole?
The concentration is 1 mol/L or 5,611 g KOH/100 mL solution.
How do you make 5 percent potassium hydroxide solution?
A solution that is refered to as a percentage of something (like potassium hydroxide, KOH) refers to the mass of the solute compared to the total solution, so a 5% KOH solution would be 5g KOH + 95g H2O, and the 5g KOH would be 5% of the 100g total of the solution.
How many grams of KOH are present in 31.5 mL of a 7.26M KOH solution?
The answer is 12,831 g KOH.
Why use ethanolic KOH?
ethanolic KOH can precipitate the impurities in solution
How many grams of KOH are in 37.5 mL of 4.96M KOH solution?
The answer is10,436 g.
How to prepare 0.1 KOH solution?
Take 5.7g of KOH and dissolve in 1dm of water
How many moles of KOH are contained in 750. mL of 5.00 M KOH solution?
Molarity = moles of solute/volume of solution 0.500 M KOH = moles KOH/125 ml 62.5 millimoles, or to answer the question precisely, 0.0625 moles KOH
