Statement I: Ti+2, V+2, Cr+2 are good reducing agents Statement II: EM+3oM+2 is highly negative for the above species

EM+3/M+2 of Ti, V and Cr is highly negative, so the ions Ti2+, V2+ and Cr2+ are strong reducingagents and will liberate hydrogen from a dilute acid, e.g.,2 Cr2+(aq) + 2 H+(aq) → 2 Cr3+(aq) + H2(g)
