Titanium dioxide is a type of mixture if particles of titanium dioxide are insoluble in the liquid.
<h3>What is a mixture?</h3>
A mixture is composed of one or more pure substances in varying compositions.
A mixture is a material made up of two or more components joined together, but not chemically combined. In a mixture, a chemical reaction does not occur and each of its components maintains its identity and chemical properties.
A compound is a substance formed by the chemical combination of two or more different elements from the periodic table. The elements of a compound cannot be divided or separated by physical processes. They are not mixtures or alloys
An element is a type of matter made up of atoms of the same class. It is an atom with unique physical characteristics, a substance that cannot be decomposed by a chemical reaction.

Answer:
The pH of the solution is 2.873
Explanation:
<u>Given:</u>
- Pka = 3.89
- pH of a 0.0140 M
Let the solution of the uric acid be HA. We have to set up the ICE table as follows;
HA(aq) + H20(l) ⇄ H3O^+(aq) + A^-
I 0.0140 0 0
C -x +x +x
E 0.0140 - x x x
Ka = 10^-(pka)
= 10^-3.89
= 1.28 x 10^-4
Ka = [H+] * [A-]/[HA]
=> 1.28 x 10^-4 = [H+]^2 / 0.0140
=>[H+]^2 = 1.28 x 10^-4 x 0.014
=> [ H+] = 1.338656 x 10^-3
so pH = - log [ H+ ] = - log 1.338656 x 10^-3
= 3 - log 1.338656
= 2.87333101111
