It runs from 0 to 14. (A)
It is based off the -log [H+] where [H+] is the concentration of the Hydrogen ions.

When carbonate sediments are subjected to thermal or regional metamorphism, the CO2 cannot often escape and the carbonate minerals simply recrystallize; calcite and dolomite commonly form marble. Carbonate minerals can therefore be common in some metamorphic rocks.
In science, physical quantities like length, weights etc are measured in units of metric or International System of units.
Some importance units are as follows:
1. Meter (m) for length.
2. Liter (L) for volume.
3. Gram (g) and kilogram (kg) for mass.
4. Degree Celsius (oC) for temperature.
5. Second for (s) time.
Given that the length of an object = 45.2 cm
SI unit of length is m
100 cm = 1.0 m
Therefore
45.2 cm * 1 .0 m/100 cm
= 0.452 m
<u>Given:</u>
Volume of the unknown monoprotic acid (HA) = 25 ml
<u>To determine: </u>
The concentration of the acid HA
<u>Explanation:</u>
The titration reaction can be represented as-
HA + NaOH → Na⁺A⁻ + H₂O
As per stoichiometry: 1 mole of HA reacts with 1 mole of NaOH
At equivalence point-
moles of HA = moles of NaOH
For a known concentration and volume of added NaOH we have:
moles of NaOH = M(NaOH) * V(NaOH)
Thus, the concentration of the unknown 25 ml (0.025 L) of HA would be-
Molarity of HA = moles of HA/Vol of HA
Molarity of HA = M(NaOH)*V(NaOH)/0.025 L
