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.

How do you make a 10 percent aqueous solution of potassium hydroxide?

To make a 10 percent aqueous solution of potassium hydroxide, you would dissolve 10 grams of potassium hydroxide in enough water to make a total solution volume of 100 mL. This solution would be considered a 10 percent concentration by weight. Be cautious when handling potassium hydroxide as it is a caustic substance.


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 sodium hydroxide must be dissolve in 200 g of water to produce a 4.00 percent by mass aqueous sodium hydroxide solution?

4.00% (percent) by mass (weight) means 4.00g for each 100g of solution. There are 2 x 100g of water, so 2 x 4g =8.00g of NaOH (sodium hydroxide) But, a 4% aqueous solution of NaOH should mean it's 96% (96g) water. There are 2.08333 x 96g of water, so 2.08333 x 4g = 8.33g of NaOH.


How much does 50 percent potassium hydroxide weigh per gallon?

The weight of 50% potassium hydroxide per gallon is approximately 10.49 pounds.


A chemist dissolves 3.50 g of potassium iodate and 6.23 g of potassium hydroxide in 805.05 g of water what is the percentage concentration of each solute in the solution?

The specified amounts of materials add to 814.78 grams total. Therefore, the percentage concentration by mass of potassium iodate is 100(3.05/814.78) or 0.374 percent, to the justified number of significant digits, and the percentage concentration by mass of potassium hydroxide is 100(6.23/814.78) or 0.765 percent, to the justified number of significant digits.

What is the meaning of 50 percent NaOH aqueous solution?

A 50% NaOH aqueous solution means that the solution contains 50% sodium hydroxide (NaOH) by weight and the rest is water. This concentration indicates that for every 100 grams of the solution, 50 grams is NaOH.

Why1.2 percent water solution of potassium chloride used in UV calibration?

The solution of potassium chloride is used to evaluate the stray light.


What is the answer of what is the weight percent of potassium nitrate in a solution that is made by dissolving 30.0 g of potassium nitrate in 90.0 g of water?

To find the weight percent of potassium nitrate in the solution, first calculate the total mass of the solution, which is the sum of the mass of potassium nitrate and the mass of water: 30.0 g + 90.0 g = 120.0 g. Next, use the formula for weight percent: (mass of solute / total mass of solution) × 100%. Thus, the weight percent of potassium nitrate is (30.0 g / 120.0 g) × 100% = 25.0%.


Formalin is 40 percent aqueous solution of which acid?

Formalin is 40% solution of formaldehyde not an acid.


How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?

To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.


What amount of solid Naoh must be added to 750g of an aqueous solution to make 2.5 percent naoh solution by mass?

You would need to add 18.75g of solid NaOH to the 750g of aqueous solution to obtain a 2.5% NaOH solution by mass.


Calculate the mole fraction of HCl in 20 percent aqueous solution?

The mole fraction of HCl in a 20% aqueous solution can be calculated by converting the percentage to a molarity concentration. Assuming the density of the solution is 1 g/mL, a 20% solution means 20g of HCl in 100g of solution. If the molar mass of HCl is 36.5 g/mol, we can calculate the molarity and then use it to find the mole fraction of HCl in the solution.
