Answer: 2.223
Explanation:
HClO4, also known as perchloric acid, is a very strong. This means we can assume that complete dissociation occurs.
This means that:
[H+] = [HClO4] = <span>0.00598
pH = -log[H+]
pH = -log[</span><span>0.00598] = 2.223
Note: The base of the log is 10 (conventionally we don't write the base if it is 10)</span>
Answer:
Both
Explanation:
Depends on which reaction reffered
Answer:
The volume of the potassium hydroxide solution was 164.1 mL
Explanation:
In the equivalence point of a titration between an acid an a base, the moles of H⁺ are equal to the moles of OH⁻.
In the case of potassium hydroxide (KOH) and hydrochloric acid (HCl), an equation that represents the equivalence point would be:

Using that equation and the data given in the problem, we can calculate the volume of potassium hydroxide:

Explanation:
Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
