nalin [4]

Answer:

[H⁺] = 0.00013 M

[OH⁻] = 7.7 × 10⁻¹¹ M

Explanation:

Step 1: Calculate the concentration of H⁺ ions

HCl is a strong acid that dissociates according to the following equation.

HCl ⇒ H⁺ + Cl⁻

The molar ratio of HCl to H⁺ is 1:1. The concentration of H⁺ is 1/1 × 0.00013 M = 0.00013 M.

Step 2: Calculate the concentration of OH⁻ ions

We will use the ionic product of water equation.

Kw = 10⁻¹⁴ = [H⁺] × [OH⁻]

[OH⁻] = 10⁻¹⁴/[H⁺] = 10⁻¹⁴/0.00013 = 7.7 × 10⁻¹¹ M

Which of the following statements are true regarding the effect of flame temperature on atomic absorbance and atomic emission sp
creativ13 [48]

Answer:

the correct option is option c, I and IV

Explanation:

Atomic emission spectroscopy is used to determine quantity of element in a sample.

Atomic emission spectroscopy based on occurring of atomic emission when a valence electron from higher energy orbital comes back to lower energy orbital.

Light intensity emitted by a flame, plasma, arc of particular wavelength are used to excite the valence electron.

The intensity of atomic emission lines are proportional to number of atoms present in the excited state.

Emission intensity is affected by temperature of the excitation source and the efficiency of atomization.

Increase in temperature does not affect the ground state population.

Therefore, statements I and IV are correct.

So, the correct option is c.
