If i will go with finding the equivalent wt of naoh in this reaction:NAOH+HCL=NACL+H2Ohere AS WE KNOW THAT 1 MOL OF HCL MEANS 1 EQUIVALENT OF IT AND 1 MOL OF H2O(WATER) MEANS 2 EQUIVALENT OF IT.BUT IN THE ABOVE REACTION IF I GO LIKE THAT THE LAW OF EQUIVALENCE WILL BE VIOLATED BCOZ HCL WOULD BE 1 EQUIVALENT AND H2O WOULD BE 2 EQUIVALENT.WHERE I'VE COMMITTED THE MISTAKE?PLS ANALYSE THE CONCEPT OR REFER ME TO READ SOME BOOKS ON IT!And yeah i know this problem can also be solved by using thag formula,if naoh contains 2 parts of OH then the equivalent of NAOH will be 1/2.i don't wanna solve it frm this method.bt as this is also derived from the same concept that the combination of hydrogen of 1 part.thewhy'm i getting the ambiguous situation in the above method.And if i assume that in the above reaction equivalents of hcl would be 1 only means 1 mol of H2O contains 1 equivalent of it means 1 equivalent of hydrogen and 1 equivalent of oxygen.so in case of hydrogen 2 moks of hydrogen means 1 equivalent of it.means 1 equivalent of hydrogen contains 2 mol of it and hence the definition itself is changed.the whole equivalent concept will go wrong,bcoz we consider hydrogen as a standard atom in equivalent concept and its 1 equivalent should 1 mol of it only.pls help!!!!!
