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 many grams of KOH are present in 31.5 mL of a 7.26M KOH solution?
The answer is 12,831 g KOH.
In which solution will thymol blue indicator appears blue?
KOH
How many grams of solid KOH is necessary to prepare 60ml of 2M KOH solution?
Moles KOH = Molarity x Volume = 0.214 moles/liter x 0.0602 liters = 0.0129 moles KOH. Remember, 60.2 mL = 0.062L
Do KOH when dissolved in water conduct electricity?
Yes, because KOH is highly ionic in nature and water being polar in nature is a very good solvent for KOH and forms a solution. The reaction is heat generating and called Exothermic Reaction.
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?
How many moles of potassium hydroxide are required to prepare 300 mL of 0.250 M solution?
Molarity = moles of solute/liters of solution ( 300 ml = 0.300 liter ) 0.250 molar KOH = moles KOH/0.300 liters = 0.075 moles KOH
If 25.0 ml of 1.48m h2so4 can be neutralized with 27.29 ml of koh what is the molarity of the koh?
25 milliliters of the solution has . 037 moles of H2SO4. The neutralization reaction is H2SO4 + 2 KOH yields 2 H2O + K2SO4. So, . 074 moles of KOH are required. This equals 2. 71 mL of solution.
30 ml of hydrofluoric acid hf is titrated with a solution of 0.10 m koh if 55 ml of koh is required to reach the equivalence point what is the concentration of the acetic acid solution?
0.13 is the concentration of the acetic acid solution.
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.
Why alcoholic potassium hydroxide is used for calculating saponification number of oil?
because alcohol is required for dissolving both KOH and lipid
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
