When electrons in atom interaction with light or photons one of the two process takes place:
1) they can absorb photons of a characteristic wavelength (which depends on the energy difference between two interacting atomic levels) and get excited to a higher energy level
2) or they can jump to a lower energy level and emit photons of the corresponding wavelength.
The type of spectrum produced when electrons in an atom undergo transitions to various levels by absorbing or emitting photons is termed as atomic spectrum.
Explanation:
this is the balanced equation
Answer:
10.1 M
Explanation:
Applying,
pH = -log(H⁺).................... Equation 1
But,
[H⁺][OH⁻] = 1×10⁻¹⁴................ Equation 2
Where [H⁺] = Hydrogen ion concentration, [OH⁻] = Hydroxyl ion concentration.
From the question,
Given: [OH⁻] = 1.25×10⁻⁴ M
Substitute into equation 2
[H⁺][1.25×10⁻⁴] = 1×10⁻¹⁴
[H⁺] = 1×10⁻¹⁴/1.25×10⁻⁴
[H⁺] = 0.8×10⁻¹⁰ M
[H⁺] = 8×10⁻¹¹ M
Also, Substitute the value of [H⁺] into equation 1
pH = -log[8×10⁻¹¹]
pH = 10.1 M
