How many milliliters of 0.200 m naoh will be required to titrate 10.5 ml of 0.479 m h2so4

Ans: Volume of NaOH needed = 50.3 ml

Given:

Molarity of NaOH = 0.200 M

Molarity of H2SO4 = 0.479 M

Volume of H2SO4 = 10.5 ml

To determine:

Volume of NaOH required

Explanation:

The titration reaction can be shown as:

2NaOH + H2SO4 → Na2SO4 + 2H2O

Based on the reaction stoichiometry:

2 moles of NaOH reacts with 1 mole of H2SO4

i.e.

moles of NaOH required = 2(moles of H2SO4)

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
