Plz tell that for definition of enthalpy of neutralisation why can't we use i mole...as the actual definition is for 1 gram equivalentof acid and base

sir but all enthalpies like enthalpy of combu. ,enthalpy of formation , are defined for 1mole but how this definition valid if we say that for neutralisation 1mol of h2so4 we ha...

For HCl Gram equivalent=molar mass/ 1 as it's 1 mole will give 1 mole of H+

That's why we use equivalent.

yes sir ...I got the answer

if you have problem in equivalent....see an equivalent is the number of moles of an ion in a solution multiplied by the valence of that ion. If 1 mol of NaCl and 1 mol of CaCl2 dis...
