Question

Ce concentratie normala are o solutie de H2SO4 98% si densitatea de 1.84 g/cm^3?

Answer 1

Cn = md/EgxVs

Eg = echiv. gram = miu/nr. H+ = 98/2 = 49 g

ro = p = ms/Vs => ms = pxVs

c% = mdx100/ms => ms = mdx100/c

=> ms = ms => pxVs = mdx100/c <=> cxpxVs = mdx100

=> md = cxpxVs/100

=> md = CnxEgxVs

md = md => cxpxVs = 100xCnx49xVs , Vs se simplifica

=> Cn = cxp/100 = 98x1,84/49x100 = 0,037 N
