How do you make a 1 percent aqueous solution of potassium hydroxide?
To make a 1% aqueous solution of potassium hydroxide, you would mix 1 gram of potassium hydroxide with 99 grams of water (for a total of 100 grams solution). This would give you a solution where 1% of the total weight is potassium hydroxide.
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.
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
No, potassium hydroxide cannot be made by mixing potassium sulfate and calcium hydroxide. Potassium hydroxide is typically produced through the electrolysis of potassium chloride. Mixing potassium sulfate and calcium hydroxide would not result in the formation of potassium hydroxide.
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.

To make a 1% aqueous solution of potassium hydroxide, you would mix 1 gram of potassium hydroxide with 99 grams of water (for a total of 100 grams solution). This would give you a solution where 1% of the total weight is potassium hydroxide.
What is the Product of potassium sulphate potassium hydroxide water and Potassium manganese?
The product of potassium sulfate and potassium hydroxide will be potassium sulfate and potassium hydroxide since they are already compounds. When water is added to the mixture, it will dissolve the compounds and create a solution. Adding potassium manganese to the solution would result in a mixture of all the substances present.

What volume of a 0.152 M potassium hydroxide solution is required to neutralize 10.2 ml of a 0.198 M hydrochloric acid solution?
To determine the volume of potassium hydroxide solution needed to neutralize the hydrochloric acid solution, you can use the formula M1V1 = M2V2. By plugging in the given values, you can calculate the volume of the potassium hydroxide solution required. In this case, the volume of the 0.152 M potassium hydroxide solution needed to neutralize 10.2 ml of the 0.198 M hydrochloric acid solution would be 7.43 ml.
If you use potassium hydroxide instead of sodium hydroxide what salt would you make?
If you use potassium hydroxide instead of sodium hydroxide, you would make potassium salts instead of sodium salts. For example, if you reacted potassium hydroxide with hydrochloric acid, you would produce potassium chloride.
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
How do you prepare 0.1 n alcoholic potassium hydroxide solution?
To prepare a 0.1 N alcoholic potassium hydroxide solution, you would mix potassium hydroxide pellets with a calculated amount of alcohol, such as ethanol, in a specific volume to achieve the desired concentration. It is important to handle potassium hydroxide with care due to its corrosive nature, and protective equipment should be worn during preparation. After mixing the components thoroughly, the solution should be standardized using a suitable acid to verify its concentration.
What happens when lithium reacts with potassium hydroxide solution?
There will be no reaction between the lithium and the potassium hydroxide. However, since the potassium hydroxide is in solution, the lithium will still react with the water to form lithium hydroxide and hydrogen gas. 2Li + H2O --> H2 + LiOH.
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
No, potassium hydroxide cannot be made by mixing potassium sulfate and calcium hydroxide. Potassium hydroxide is typically produced through the electrolysis of potassium chloride. Mixing potassium sulfate and calcium hydroxide would not result in the formation of potassium hydroxide.
What acid and base would react in a aqueous solution to produce potassium iodide?
Acid is Hydroiodic Acid (HI) and the Base (Alkali) is potassium hydroxide. Here is the reaction eq'n. HI(aq) + KOH(aq) = KI(aq) + H2O(l).
Will using potassium hydroxide during electrolysis produce chlorine gas?
If you mean just potassium hydroxide or its aqueous solution, then no, because their are no chlorine atoms present. The only elements present are potassium, hydrogen and oxygen. Molten KOH produces potassium at the cathode and oxygen at the anode, and the solution gives hydrogen at the cathode and oxygen at the anode.
