What is the pH of a 0.0001 M solution of potassium hydroxide?
potassium hydroxide: KOH you'll need the Ka of it, Ka = [OH-][K+] / [KOH] ; OH and K have the same concentrations, so they're equal, so they can be represented by x. when you have the concentration of OH then you multiply it by -log[OH-], but then you'd have pOH, so just do 14-[-log[OH-]
What volume of nitrous oxide gas has the same number of atoms as 9.00L od neon gas at same temperature and pressure?
9L
Balanced equation for potassium carbonate?
Perform a acid-base titration with a strong acid with a known concentration. Don't forget to measure the exact mass or the molarity of KOH/K2CO3.Repeat this determination several times to find the right equivalence point, this is important by these kind of quality controls. Then you can calculate the molar ratio of KOH/K2CO3.(V*C)acid = (V*C)base C= concentration and V = volume
What volume mL of a concentrated solution of sodium hydroxide 6.00 M must be diluted to 200.0 mL to make a 0.880 M solution of sodium hydroxide?
use titration formula
What is the concentration of a solution with a volume of 0.50 L that contains 40.0 grams of sodium hydroxide?
2.0 M
What volume of a 0.550 M solution of potassium hydroxide can be made with 10.7g of potassium hydroxide?
347 mL
What is Potassium Hydroxide on the pH scale?
It will have a basic pH ranging from just above 7 to 14. The precise pH depends on how much of the KOH is in a given volume.
What volume of 2500 M strontium hydroxide is required to completely react with 75ml of 07942 M HCL?
11.91 mL
What are the steps to do the biuret test?
1) Add 2cm3 of solution to be tested to a test-tube. 2) Add an equal volume of 5% potassium hydroxide* solution and mix. 3) Add 2 drops of 1% copper sulphate solution and mix. A mauve or purple colour develops if protein is present. *Sodium hydroxide solution can be used instead of potassium hydroxide solution.
What volume of a 0.55m solution of potassium hydroxide can be made with 19.9 g of potassium hydroxide And please show me how to figure this out?
The first thing you need to do is convert your grams of potassium hydroxide into moles. Potassium hydroxide has the formula KOH. The atomic weights are as follows: K: 39.098 g/mol O: 15.999 g/mol H: 1.0079 g/mol Add them together and you get a formula mass of 56.1049 g/mol. So now divide the mass by this value. 19.9g/56.1049 g/mol = 0.354 mol. Molarity is moles divided by volume. M=n/V Since we are solving for volume we have to rearrange the equation. M*V=n V=n/M So we divide the number of moles by the molarity to get the volume. 0.356 mol/0.55M =0.64 l. So you would need 0.64 liters of water to obtain the desired concentration.
Volume of nitrous oxide in a 3.4 kg cylinder?
At STP is 2.18L
A volume of 40.0g of aqueous potassium hydroxide was titrated against a standard solution of sulfuric acid. What was the molarity of the solution if 25.7g of 1.50M was needed?
M = n ÷ V M-Molarity (mol/l) n- moles V- volume in liters. Volume cannot be expressed in grams....
How many molecules are in 100 L of potassium hydroxide solution at STP?
The number of molecules in a given volume of solution depends on the concentration of the solute. Because the concentration is not provided, this question has too little information to answer.
What is potassium's atomic volume?
Atomic Volume (cc/mol): 45.3
The volume in ml of 2.26m potassium hydroxide solution that contains 8.42g of solute?
8.42 grams of KOH is equal to 0.15 moles. If the solution has a molarity of 2.26 moles per liter, then there are 66.4 milliliters of solution.
How many grams barium hydroxide?
get the volume of the chemical and the mass and divide the mass by it's volume
How its made 2 M solution of Na OH?
First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.
