Which of the following metals will react with water to produce a metal hydroxide and hydrogen gas? mg li al pb

Actually to determine which metals will react with water to form hydroxide, we have to refer to the reactivity series. In this case, our baseline would be Hydrogen ion since it is the one being displaced by the metal in the water compound (H+ OH-) to form metal hydroxide. From the series, all metals are above hydrogen, hence all will react.

all
