Question

Exercitiul V va rog frumos

Answer 1

-calculez moli  NaOH  V= 20ml=0,02  l
C=n/V;    0,2= n/ 0,02 l---. n= 0,004 mol NaOH
-ecuatia rectiei
CH3COOH +NaOH---> CH3COONa+H2O
1mol...............1mol
n-----------------0,004mol
n= 0,004 mol CH3COOH

-CALCULEZ VOLMUL DE SOLUTIE  de acid
0,1= 0,004/ V------> V= 0,04l= 40ml
