Answer:

pH = 6.80. The aqueous solution is slightly acid

If pH is 7.00 at 37°C, solution is neutral

Explanation:

2H₂O ⇄  H₃O⁺  + OH⁻     Kw = 2.4×10⁻¹⁴

To determine the pH of a solution, we must consider the [H₃O⁺]

[H₃O⁺] . [OH⁻] = 2.4×10⁻¹⁴

[H₃O⁺] =  [OH⁻]  → √2.4×10⁻¹⁴ =  [H₃O⁺]

1.55×10⁻⁷ = [H₃O⁺]

pH = - log 1.55×10⁻⁷ = 6.80

pH = 7 → neutral

pH < 7 → acid

pH > 7→ basic

Describe the location of the negative charges of the atom in j.j thompsons plum pudding model
iren2701 [21]

The location of the negative charges is evenly distributed throughout the entire atom.

J. J. Tomson concluded that atoms are divisible and that the corpuscles are their building blocks.

Atoms are made up of smaller particles.

J. J. Thomson discovered the electron ( the negative charges of the atom) in 1897.

His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge and evenly distributed throughout the entire atom.

With this model, he abandoned his earlier hypothesis that the atom was composed of immaterial vortices.

Later, Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate.
