Answer:

1.566x10²⁴ atoms of Cl

Explanation:

In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:

<em>Moles CCl₄: 153.82g/mol</em>

100g * (1mol / 153.82g) = 0.65 moles CCl₄

<em>Moles Cl:</em>

0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl

<em>Atoms Cl:</em>

2.6 moles Cl * (6.022x10²³ atoms / mol) =

The hydroxide ions keep decreasing and the hydrogen ions increase, pH decreases.

<h3>What is hydroxide?</h3>

Hydroxide is a diatomic anion with synthetic recipe OH⁻. It comprises of an oxygen and hydrogen particle kept intact by a solitary covalent bond, and conveys a negative electric charge. It is a significant yet generally minor constituent of water. It capabilities as a base, a ligand, a nucleophile, and an impetus. Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. Hydroxide ions can act as a catalyst in different types of reactions. Hydroxide ions can function as base, ligand, nucleophile or a catalyst.
