<u></u>
What is pH and its importance?
- pH is an important quantity that reflects the chemical conditions of a solution.
- The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
- The pH is then calculated using the expression: pH = - log [H3O+].
- The solubility of an ionic compound is affected by the hydronium ion concentration.
- Addition of H₃O⁺ to the anion of a weak acid, increases the solubility of the ionic compound.
Therefore, the pH of the solution is also increased.

2. C
3. C
Explanation:
1. there are single cell organisms
2. all others are abiotic factors
3. individual is just one, population is one species, community is all populations, ecosystem includes abiotic and biotic factors, biome is a large geographical area.
(I think you have a mistake in your question as the addition is 30mL, not 100mL)
when PH = - ㏒[H+]
and here we have HClO4 is the strong acid
So PH = - ㏒[HClO4]
moles of HClO4 = 0.1 L *0.18 m = 0.018 M
moles of LiOH = 0.03 L * 0.27 m = 0.0081 M
when the total volume = 0.1L + 0.03L = 0.13 L
∴ [HClO4] = (0.018-0.0081)/0.13 L
= 0.076 M
PH = -㏒ 0.076
= 1.12
Examples include carbonated water (i.e. soda water); honey; sugar syrup (used in confectionery); supersaturated drug delivery systems. "SDDS"; and sodium acetate solutions prepared from 160 g NaOAc and 30 mL water.
