Question

how many mLof a 9M h2so4 solutin is neededto make a 0.25L of a 3.5M h2so4 solution

Answer 1

Answer:

97.2 ml

Explanation:

when it is to be taken either for only acidic solutions or fr only basic solutions u need to take like N1V1=N2V2

Additional information:

but when they had given both acidic and basic solution then u need to calculate which concentration is more

then if acid concentration is more it is acidic solution then it gives out H+ ion concentration.

[H+]=NaVa-NbVb/Va+Vb

if base concentration is more then it gives out OH- concentration

[OH-]=NbVb-NaVa/Va+Vb
