Which statement is true about sodium hydroxide (NaOH)?

Chemistry
2 answers:
aleksley [76]3 years ago

<u>Answer:</u> The correct answer is it is a base because it increases the concentration of hydroxide ions.

<u>Explanation:</u>

An acid is defined as the chemical specie which donates hydrogen ion when dissolved in water.

HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)

A base is defined as the chemical specie which donates hydroxide ion when dissolved in water.

BOH(aq.)\rightarrow B^+(aq.)+OH^-(aq.)

A salt is formed when an acid reacts with base. This is known as neutralization reaction.

NaOH is considered a base because it produces sodium and hydroxide ions when dissolved in water.

NaOH(aq.)\rightarrow Na^+(aq.)+OH^-(aq.)

Hence, the correct answer is it is a base because it increases the concentration of hydroxide ions.

The answer is; It is salt because it is formed by the reaction of an acid and a base.


Salt is composed of cations and anions (with a net charge of 0) joined together by ionic bonds attributed to their complementary charges. NaOH is an alkali salt because it forms an alkaline solution when dissolved in water – because it dissociates hydroxide ions.

You have 1 mole of a gas at STP. If you apply the ideal gas law what is the approximate volume of the gas?
goldfiish [28.3K]

Answer:

A) 22.4L

Explanation:

we know, ideal gas law states

PV=nRT

V=nRT/P

At STP,

T= 273.15K     P=1atm         R=0.082L.atm/mol/K          n=1 mole

V=(1*0.082*273.15)/ 1

V=22.4L
