Dobrý deň v práci SOČ potrebujem 10% roztok HCl a 10% roztok NaOH, ktoré chcem pripraviť do baniek s objemom sto mililitrov
Chcel by som sa spýtať, že ako si mám vypočítať, že koľko danej látky bude treba navažiť, alebo odmerať
V laboratóriu máme k dispozícii štvormolárny roztok kyseliny chlorovodíkovej
dakujem
