First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.
12.5 mL of NaOH solution
Explanation:
We have the following chemical reaction in which sodium hydroxide (NaOH) react with acetic acid (CH₃-COOH) to form sodium acetate (CH₃-COONa) and water (H₂O):
NaOH + CH₃-COOH → CH₃-COONa + H₂O
molar concentration = number of moles / volume
number of moles = molar concentration × volume
number of moles of CH₃-COOH = 0.2 × 12.5 = 2.5 mmoles
*typically a vinegar solution have a concentration of acetic acid of 12.5 mol/L.
Taking in account the chemical reaction, we devise the following reasoning:
if 1 mmole of NaOH reacts with 1 mmole of CH₃-COOH
then X = 2.5 mmoles of NaOH reacts with 2.5 mmoles of CH₃-COOH
volume = number of moles / molar concentration
volume of NaOH solution = 2.5 / 0.2 = 12.5 mL
