Is the following salt an acid, base, or neutral? nh4clo4

It is a neutral salt, because it cannot be an acid (it needs a positive hydrogen ion at the beginning of the molecular structure) and it cannot be a base (it needs a negative hydroxide ion at the end of the molecular structure)

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
