Titration Problem
30 mL of 0.6M HCl solution is neutralized by 90 mL of NaOH solution. What’s the concentration of the base?
• We will be using the MAVA = MBVB formula. Let’s figure out the molarity and volume of the acid and the base. You can make a chart to organize the information.
• Now let’s plug in this information to the formula. Use the formula key to know what each letter stands for.
(0.6)(30) = (X)(90) 18 = 90X
X = 0.2M
Acid: HCl
Base: NaOH
Molarity
0.6M
X (We don’t know)
Volume
30mL
90 mL
