Answer:
The change in concentration of H+ ions is -9.99×10⁻⁵
Explanation:
When pH rises, we talk about neutralization and, there is a decline in proton's concentration.
pH lower than 7 is acid
pH higher than 7 is basic
Protons are neutralized by hydroxides to make water as this:
H₃O⁺ + OH⁻ ⇄ H₂O
pH = - log [H₃O⁺]
[H₃O⁺] = 10^-pH
In conclussion: [H₃O⁺]₁ = 10⁻⁴ → 1×10⁻⁴
[H₃O⁺]₂ = 10⁻⁷ → 1×10⁻⁷
1×10⁻⁷- 1×10⁻⁴
The change in concentration of H+ ions is -9.99×10⁻⁵
Answer:
is Bronsted Lowry base.
is Bronsted Lowry acid.
Explanation:
According to the Bronsted Lowry conjugate acid-base theory:
- An acid is defined as a substance which donates protons and form conjugate base
- A base is defined as a substance which accepts protons and forms conjugate acid.
is Bronsted Lowry base.It accepts protons and forms conjugate acid 
is Bronsted Lowry acid.It donates protons and forms conjugate base 
There in no exchange of proton in an above reaction.Neither of the reactants and products are Bronsted Lowry acid or Bronsted Lowry base
Answer:
69.152 % → 63Cu
30.848 % → 65Cu
Explanation:
As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.
