What are KOH pellets?
Potassium (K) Hydroxide (OH) pellets.
How do you prepare a 10N naoh solution with pellets?
Make sure to use goggles and gloves, because sodium hydroxide is very caustic, and the mixture can get very hot (reaction is very exothermic). 1) Weigh out 400 grams (10 moles) of NaOH pellets. 2) Place 1 liter of water in a large borosilicate beaker (at least 2 liter volume) or other container that can handle very caustic substances. 3) Begin slowly adding NaOH pellets to your beaker or container and stirring. If using a glass container, you may want to have it set in an ice bath from the beginning to keep the temperature down, since the solution will begin to get hot as the sodium hydroxide dissolves. Continue until all of the pellets have dissolved in the 1 liter of water. This will produce a 10 molar solution of NaOH. Since 1 mole of NaOH dissociates in water to form 1 mole of Na+ ions and 1 mole of OH- ions, this will also produce a 10 N (in terms of normality) solution of NaOH.
Is NaOH a salt?
Yep, because....Sodium hydroxide (NaOH), also known as caustic soda, is a caustic metallic base. Pure sodium hydroxide is a white solid available in pellets, flakes, granules, and as a 50% saturated solution. It is hygroscopic and readily absorbs carbon dioxide from the air. Sodium hydroxide is neutralized with hydrochloric acid to produce the soluble salt sodium chloride in solution. This solution is then concentrated and crystallized to produce sodium chloride crystals.Sodium hydroxide is predominantly ionic, containing sodium cations and hydroxide anions. The hydroxide anion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts. Sodium hydroxide reacts with protic acids to give water and the corresponding salts. This type of reaction with a strong acid releases heat, and hence is referred to as exothermic. Such acid-base reactions can also be used for titrations. However, sodium hydroxide is not used as a primary standard because it is hygroscopic and absorbs carbon dioxide from air.
Would the enthalpy change be different if solid sodium hydroxide pellets were added to hydrochloric acid instead of adding hydrochloric acid to sodium hydroxide solution?
Yes, the reaction involving the solid is actually an individual step in the equation of the reaction between the solutions. If you were to add the change in enthalpy of the reaction with the solid NaOh to the change in enthalpy of the other step in the reaction (that's adding water and the NaOh pellets) you would find the sum equivalent to the change in enthalpy of the reaction involving the two solutions (this is supported by Hess's law). I suggest that you consider Hess's law for more information.
Why is potassium hydroxide important when using a respirometer?
A simple whole animal respirometer designed to measure oxygen uptake or CO2 release consists of a sealed container with the living specimen together with a substance to absorb the carbon dioxide given off during respiration, such as soda lime pellets or cotton wads soaked with potassium hydroxide.
How do you prepare a 0.4 molar solution of sodium hydroxide from 96 percent sodium hydroxide pellets?
16.5g 97% pure NaOH pellets dissoved in 1 litre of distilled
What are KOH pellets?
Potassium (K) Hydroxide (OH) pellets.
Does concentrated phosphoric acid react with pure sodium hydroxide pellets?
Yes, indeed!
How is sodium hydroxide available in the laboratory?
Usually in the form of tiny spherical white pellets.
How do you prepare 30 percent sodium hydroxide?
Actually a 50% solution of sodium hydroxide would be made using enough water to total 100 mL of solution if using sodium hydroxide pellets or crystals. 50% of the total weight of the solution not 50% of the weight of the water used. As suggested by the first answer, the solution would be about a 33% solution. percentage solutions are weight for weight. Therefore 50% solution would be 50g of sodium hydroxide dissolved in 100g (100mL) of water.

What is the standad test for carbon dioxide?
Put a lighted splint into the gas container and if it goes out it could be CO2. - absorption in a Ca(OH)2 solution: the suspension become milky. - adsorption on sodium hydroxide impregnated asbestos pellets: gravimetric analysis - spectrometry with infrared sensors Pass the gas through limewater, if it goes cloud then carbon dioxide is present.
Why should the Na OH pellets be completely dissolved in the preparation of the Na OH solution?
Well the point of a solution is that any solids involved are dissolved. Otherwise there is never any chance of having a homogenous solution (equal concentration, anywhere in the volumetric flask)
Why is potassium hydroxide important when using a respirometer?
A simple whole animal respirometer designed to measure oxygen uptake or CO2 release consists of a sealed container with the living specimen together with a substance to absorb the carbon dioxide given off during respiration, such as soda lime pellets or cotton wads soaked with potassium hydroxide.
What can the pellets be used for?
In fact, many products appear in forms of pellets. They can be used in many fields like animal feed pellets, bedding pellets and home heating pellets,etc.
