Moist silver is highly prone to attack by hydrogen sulphide or any other potential source of sulphide(S2-). Silver reacts with sulphide forming black silver sulphide, which is an insoluble salt of silver. Consequently silver utensils/articles turn black.
Hence, it is advisable to wipe off water immediately from silver articles/utensils post wash to prolong its attack by sulphide.
