The formula "K" refers to potassium hydroxide. When dissolved in methanol (OH), it becomes KOH, or methanolic potassium hydroxide. This is an extremely volatile liquid, so the utmost care must be taken in preparation.
Dissolve 30 g KOH in 100 mL methanol.
To prepare 0.1M methanolic HCl: 8ml water in 1000ml vol. flask. slowly add 8.6ml HCl. vol. make upto mark with methanol.
Molar mass KOH = 56g/mol and 0.002 N KOH = 0.002 moles/L0.002 moles/L x 56 g/mole = 0.112 g/LDissolve 0.113 grams KOH in 1 liter or methanol, or any fraction/multiple thereof. For example, dissolve 0.0113 g KOH in 100 mls or dissolve 0.226 g in 2 liters of methanol.
Take 5.7g of KOH and dissolve in 1dm of water

Dissolve 30 g KOH in 100 mL methanol.
Dissolve 30 g potassium hydroxide in 100 mL methylic alcohol.
To prepare 0.1M methanolic HCl: 8ml water in 1000ml vol. flask. slowly add 8.6ml HCl. vol. make upto mark with methanol.
make sure to sudy it alot
KOH is used to prepare liquid soaps.

We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.

really you dont know? well.....I dont either! blood is ment to sqeese through muscles then thats bad but thats wat i heard!
Molarity = moles of solute/Liters of solution ( 220.0 ml = 0.220 Liters ) 0.500 M KOH = moles KOH/0.220 Liters = 0.110 moles KOH (56.108 grams/1 mole KOH) = 6.17 grams solid KOH needed
You weight 14,5 gramm KOH in a bottle and than fill that bottle with deionized water till it holds 500ml.
