Question #350890

How many mL of 0.25M solution of H2SO4 will react with 10mL of 0.25M solution of NaOH?

Expert's answer

C_{M} — concentration of molarity (mol/L)

V — volume (L)

n — amount of substance (mol)

C_{M} (NaOH) = 0.25 M

V (NaOH) = 10 ml = 0.01 liters

"n(NaOH)=~C_M*~V =~ 0.25 * ~0.01 = ~0.0025 ~mol"

2NaOH + H_{2}SO_{4} = Na_{2}SO_{4} + 2H_{2}O

2 mol NaOH — 1mol H_{2}SO_{4}

0.0025 mol NaOH — X

X = 0.0025*1/2= 0.00125 mol H_{2}SO_{4}

"V(H_2SO_4)=~\\cfrac {n}{C_M}= ~\\cfrac {0.00125}{0.25}=~ 0.005 L=~5~ml"

**Answer: 5 ml**
