Titration in the Lab
Part of the Food Chemistry and the Lab section of Coddy's Chemistry journey. Lesson 22 of 27.
A titration: base from a burette into an exact volume of acid with an indicator, until the color just changes, the end point.
At the end point the moles of OH⁻ added equal the moles of H⁺
For HCl and NaOH (one to one): c_a V_a = c_b V_b.
H₂SO₄ gives two H⁺: each mole of it needs two moles of NaOH.
Challenge
In a titration, of NaOH neutralizes of hydrochloric acid:
HCl + NaOH → NaCl + H₂O
What is the concentration c_a of the acid?
