Answer:
the overall cell potential
Explanation:
We must bear in mind that the standard hydrogen electrode is a reference electrode whose electrode potential has been arbitrarily set at 0 V.
The standard hydrogen electrode consists of hydrogen ion solution and hydrogen gas together with a platinum electrode.
The overall cell potential is the reduction potential of the substance being determined using the standard hydrogen electrode as a reference electrode since its electrode potential is set at zero volts.
Because electrons are negatively charged so losing an electron leaves the atom with positive charge. <span />
Answer:
O the molecular formula
Explanation:
The true ratio of atoms in a molecule or formula unit is called the molecular formula.
The molecular formula of a compound shows the true number of atoms that are combining to form a compound.
For example, the molecular formula of water is H₂O.
- Empirical formula of a compound is its simplest ratio.
- When the number of atoms are divided by the smallest possible factor, it yields the empirical formula.
ANSWER
Option A
EXPLANATION
Arrhenius defines an acid as a substance that will produce hydrogen ions as the only positive ion when dissolved in water.
He also defines a base as a substance that contains a hydroxide ion (OH^-).
Hence, the Arrhenius Model of acids and bases applies that is applied to the aqueous solution.
The correct answer is option A
