Answer:
pH=2.34
Explanation:
HBr -> H + Br
The dissociation it's complete, for that reason the concentration of the products is the same of HBr
[H+]=[Br-]=0.00234 M
pH= - log (0.00234)=2.34
Answer:
HF + H₂O ⇔ H₃O⁺ + F⁻
Explanation:
Bronsted- Lowery acid:
Bronsted- lowery acid is the specie which have capability to donate the proton.
Bronsted- Lowery conjugate base:
The Bronsted- Lowery conjugate base of Bronsted- Lowery acid is the specie which is formed after when an acid donate the proton.
Bronsted- Lowery base:
Bronsted- lowery base is the specie which have capability to accept the proton.
Bronsted- Lowery conjugate acid:
The Bronsted- Lowery conjugate acid of Bronsted- Lowery base is the specie which is formed after when an base accept the proton.
Chemical equation:
HF + H₂O ⇔ H₃O⁺ + F⁻
In this equation HF is acted as Bronsted- Lowery acid because it donate the proton to water. water is act as Bronsted- Lowery base. While F⁻ is the Bronsted- Lowery base and H₃O⁺ Bronsted- Lowery acid.
Depends how much sugar are you talking about. If we are under the solubility concentrations of sugar no change or very little change can be observed in the volume of the solution. The sugar molecules will occupy the intermolecular spaces of the water molecules
