What is the pH of Pepsin in NaOH?

The pH of pepsin in NaOH would depend on the concentration of NaOH added. Pepsin is an enzyme that functions best at acidic pH levels, around pH 2.0. Adding NaOH, a base, would increase the pH, potentially inactivating the pepsin enzyme as it moves away from its optimal pH range for activity.


How you prepare 0.01M NaOH solution?

Dissolve 40 grams of solid NaOH into enough water that it dissolves completely. Transfer this to a volumetric flask. Then add water until the volume of the solution is 1 liter. Care is needed as heat is generated which affects the volume. It is best to make up with water to about 2 cm short of the mark, allow to cool and then add the balance of the water.


What is the pH of 0.1m NaOH and 0.05m NaOH?

The pH of 0.1 M NaOH is approximately 13, as NaOH is a strong base that fully dissociates in water to produce hydroxide ions. The pH of 0.05 M NaOH would also be approximately 13, as the concentration of the base does not impact the basicity significantly when dealing with strong bases.


How much 2.5 M NaOH is necessary to create 500 ml of 0.100 M NaOH?

A 0.205 M solution will have 0.205 moles per liter. 250 milliliters is 1/4 of a liter, so in that sample, there will be 0.05125 moles. NaOH has a molar mass of 39.9971 grams per mole, so 2.05 grams added to 250 mL of water will make the desired solution.


How do you calculate the pH of a 0.001 M NaOH solution?

To calculate the pH of a 0.001 M NaOH solution, you can use the formula pH = 14 - pOH. Since NaOH is a strong base that completely dissociates in water, the pOH can be directly calculated as -log(0.001) = 3. Thus, the pH of the solution would be 14 - 3 = 11.

When creating a solution of a strong acid and water what order should the ingredients be added?

Always add acid to water. This way if you splash what is in the container onto yourself it will be mostly water. The other way around, water to acid, and you would splash mostly acid onto yourself.


The presence of these in water causes water to conduct electicity?

Pure water, by itself, is not capable of conducting electricity. However, when other substances are added and ions make their way into water, those free ions can cause water to conduct electricity.

What other way plants can grow with out soil?

Plants can be grown by a system called hydroponics, where they are grown in a nutrient rich liquid (ie water with fertilizer added); instead of soil.

How do you prepare 6N sodium hydroxide?

There are several methods for producing sodium hydroxide, or NaOH. The most common way of making NaOH at least as long ago as several hundred years if not more than 1000 was by mixing sodium carbonate, lime, and water. Lime is calcium hydroxide, which is made by heating a mixture of water and crushed limestone. The reaction of sodium carbonate and lime in water is: Na2(CO3) + Ca(OH)2 -----> CaCO3 + 2 NaOH The calcium carbonate formed is barely soluble in water, therefore the solution of NaOH is poured, filtered, or pumped away from the calcium carbonate precipitate and the water is allowed to evaporate away. A solution of NaOH can be easily made by allowing sodium metal to react with water. However, DO NOT PERFORM THIS REACTION WITHOUT A PROFESSOR'S GUIDANCE! The reaction produces hydrogen gas and a lot of heat; enough to ignite the hydrogen and air mixture, which will cause an explosion. Today, most NaOH is made using DC electricity and seawater. The anode is immersed in, or fed filtered seawater, and it is surrounded by a semipermeable membrane through which chlorine gas cannot pass and enter the solution. At the surface of the anode, chloride ions are oxidized to chlorine gas which is captured. Of course the cathode must be in electrical contact with the anode and the ionic balance must be maintained or nothing will happen. It's impossible to remove chloride anions without either replacing them with another anion or removing an equal number of cations. When making sodium hydroxide, water is reduced at the cathode to hydrogen gas and hydroxide anions, which replace the lost chloride ions and keep the reaction going. Thus, what is left in the seawater are the sodium and hydroxide ions, plus small concentrations of other ions. Solid NaOH is made by removing the water, probably by vacuum distillation. More pure NaOH can be made by recrystallizing the initial NaOH, or ion-exchange resins may be used to remove ions other than Na+ and OH-. There may be other methods for purifying the initial NaOH. The reason the chlorine gas must be removed is because a solution of chlorine gas in sodium hydroxide forms chlorine bleach, like Clorox®.

What is added to water and not the other way around?

"Add acid to water and do what you ought-er" is the memory aid / jingle that my Freshman chemistry instructor used. It applies to most any acid.
