why is the volume of base needed to neutralize the HCl acid different from H2SO4?

Answer 1

Acid come from H atoms. Because H2SO4 has two H atoms in it, it needs twice as much base to neutralize it, compared to HCl. HCl only has one H atom in it.

i.e. H2SO4 has two H and HCl has one H

Therefore, you will need twice as much base to neutralize H2SO4 compared to HCl

Answer 2

H2SO4 has a higher concentration of H+ Ions in it as compared to HCl.

You'll see that the concentration of H+ ions in HCl is lower than the concentration of H+ ions in H2SO4.

The higher the concentration of H+ ions, the more base is needed to neutralize it.

Answer 3

the 1st step is often to transform the concentration (which you categorised N by using mistake, it is going to be M for molarity) and quantity of NaOH into moles. n = C x V (V might desire to be in litres) n = 3 x 384/one thousand n = a million.152 moles of NaOH Now we are able to evaluate the form of moles applying the huge numbers from a balanced equation this is declared as the mole ratio. HCl + NaOH --> NaCl + H2O As you will locate there are no huge numbers in front of the chemical components so this implies they're all a million so shown right here 1HCl + 1NaOH --> 1NaCl + 1H2O this implies a million mole of NaOH reacts with a million mole of HCl, yet we've a million.152 moles of NaOH so it reacts with a million.152 moles of HCl. we've now the moles of HCl and the concentration so we are able to artwork out the vol (in litres) v = n/C v = a million.152/2 v = 0.576 litres or 576mL.

Answer 4

Moles of H+.
