Question

Calcular el PH de:
NaOH 0.80M
Ba(OH)2 0.30M

Answer 1

Calcular el PH de:

NaOH 0.80M
pOH = -log [OH⁻]pOH = -log [0.80]pOH = -(-0.097=pOH = 0.097pH +pOH = 14  despjar pHpH = 14 - pOHpH = 14 - 0.097pH = 13.903
Ba(OH)2 0.30M

pOH = -log [OH⁻]

pOH = -log [0.30]
pOH = -(-)-0.522)pOH = 0.522pH +pOH = 14  despjar pHpH = 14 - pOHpH = 14 - 00.522 = 13.478
