Is excess sodium hydroxide soluble in water?

Answer 1

First off, the question is worded in such a way that it is not true simply by definition. Sodium hydroxide is a solid, and therefor a liquid (alcohol) could never be soluble (dissolved inside of) a solid.

If you properly ask the question as, "Is sodium hydroxide soluble in alcohol?" we can answer the question.

Yes, sodium hydroxide is soluble in water, ethanol and methanol.

The solubility of NaOH in water is 111 g / 100 mL H2O.

Solubility in methanol: 23.8 g/100 mL

Solubility in ethanol: 13.9 g/100 mL

Answer 2

Yes, excess sodium hydroxide is soluble in water. Sodium hydroxide is a strong base that readily dissociates into sodium cations and hydroxide anions in water, making it highly soluble in aqueous solutions.

Answer 3

You will find upon searching that alcohols are soluble in sodium hydroxide solutions, or more commonly found that sodium hydroxide is soluble in alcohols. However, this is not techically correct, because the sodium hydroxide and alcohols actually react to form alcoholates. The reaction is as follows: NaOH + R-OH <-> R-ONa + HOH The reation does not go to completion and the amount of alcoholate formation decreases with an increase in R length.

Answer 4

I just tried it out using distilled water at 23 degrees C. NO, it isn't soluble (at least not noticeably so). I used 20 mL of ethanol in a large test tube and added a pinch of reagent grade sodium carbonate. I stirred for 60 seconds with a glass stirring rod. Then I let the solution sit and settle for about an hour. There is still a pinch of sodium carbonate sitting on the bottom of the test tube. My guess is that the ethanol is not polar enough to dissociate Calcium atoms from the Carbonate ion.

Answer 5

Yes, Sodium Hydroxide forms a stron alkaline solution when dissolved in solvent such as water.
Yes. All sodium compounds do.

Answer 6

Sodium hydroxide is very soluble in water.

Answer 7

no it is just a base

Answer 8

because sodium hydroxide is a alkaline

Answer 9

Both have polar molecules.

Answer 10

no
