A solution of sodium hydroxide in water most likely to have a pH close to?
A solution of sodium hydroxide in water will have a pH greater than 7, typically ranging from 12 to 14. Sodium hydroxide is a strong base that dissociates completely in water to produce hydroxide ions, leading to a high pH.
How much does 25 percent sodium hydroxide weigh per gallon?
The weight of 25% sodium hydroxide per gallon depends on the density of the solution. Sodium hydroxide has a density close to 1.2 kg/L, so a 25% solution would weigh approximately 10 pounds per gallon.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.
When just enough acid has been added to neutralize the sodium hydroxide what will the pH be?
When just enough strong acid (e.g. HCl) is used to neutralize a strong base (NaOH), the pH should be neutral (pH = 7.0).
Why is it not advisable to use a ground glass stopper for a reagent bottle containing sodium hydroxide solution?
Over time, the sodium hydroxide will react with the smidges of carbon dioxide in air to produce sodium carbonate, the white, crusty powder that you find around the rim of plastic capped stock bottles (for example). This powder will either prevent the ground glass stopper from sealing properly and exposing the contents to more air, or will in fact cement the ground glass stopper in the bottle, and make it impossible to remove.

What has the following has the lowest pH pure water concentrated sugar solution concentrated sodium hydroxide solution gastric fluid?
The lowest pH would be found in the concentrated sodium hydroxide solution, as it is a strong base. The pH of gastric fluid is typically around 1.5-3.5, whereas pure water and a concentrated sugar solution are close to pH 7 (neutral) and slightly acidic, respectively.

This allows for a sharp and easily detectable color change at the endpoint of the titration.
Is there sodium hydroxide in the ocean?
No. You could only justify yes if you considered that there wrere sodium ions in solution along with very low quantities of OH- ions (sea water is close to neutral). There are also many other ions, such as Cl-, SO42-
When just enough acid has been added to neutralize the sodium hydroxide what will the pH be?
When just enough strong acid (e.g. HCl) is used to neutralize a strong base (NaOH), the pH should be neutral (pH = 7.0).
What rhymes with hydroxide?
Actually, no English word rhymes perfectly with "hydroxide." There are words that sound similar, such as "peroxide," but while these two may be close, they do not rhyme perfectly with each other.
Is Aluminium hydroxide acidic or alkali or nural solution?
Aluminum hydroxide is considered a neutral solution because it has a pH close to 7. It can act as an antacid to help reduce stomach acidity.
If an acid is combined with a base of equal strength the result would most likely be?
Depends what the two solutions are.....but the classic example is hydrochloric acid and sodium hydroxide. HCl + NaOH === NaCl + H2O This is a neutralization reaction that produces a salt called sodium chloride (table salt) and water.
Why is it not advisable to use a ground glass stopper for a reagent bottle containing sodium hydroxide solution?
Over time, the sodium hydroxide will react with the smidges of carbon dioxide in air to produce sodium carbonate, the white, crusty powder that you find around the rim of plastic capped stock bottles (for example). This powder will either prevent the ground glass stopper from sealing properly and exposing the contents to more air, or will in fact cement the ground glass stopper in the bottle, and make it impossible to remove.
Can you use sodium hydroxide as asubstitution of potassium hydroxide in activation process?
In most instances, sodium hydroxide is sufficiently close in chemical properties to potassium hydroxide to make each one a substitute for the other. There are some exceptions, however, and more details about the "activation process" under consideration would be needed to give a more detailed answer.
2 .What is the pH of the sodium hydroxide and hydrochloric acid mixture?
The pH of a mixture containing a strong base (sodium hydroxide) and a strong acid (hydrochloric acid) would depend on the proportions of the moles of acid and base added to the mixture. This would depend on the concentration of both the base and acid solutions and the quantities of the solutions added.
