What are the concentrations of hydroxide and hydronium ions in a solution with a ph of 10.2?
1.4 × 10–4 m h3o+ and 7.1 × 10–11 m oh–
3.8 × 10–6 m h3o+ and 2.6 × 10–9 m oh–
8.3 × 10–9 m h3o+ and 1.2 × 10–6 m oh–
6.3 × 10–11 m h3o+ and 1.6 × 10–4 m oh–

The correct option is, (D)  and

Explanation:  pH is the measure of acidity or alkalinity of a solution.

Now we have to calculate the concentration of ions.

Now we have to calculate the concentration.

Therefore, the concentration is and concentration is,

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
