Mg + acid Choose all that apply. Choose all that apply. formation of a precipitate (solution gets cloudy) bubbling disappearance of the solid change of color
Mg Magnesium is a metal and metals react with acid with evolution of H2 gas. Let HA be any monoprotic acid reacted with Mg metal then pertinent reaction is given as,
Mg(s) + 2HA MgA2 + H2 (g)
MgA2 is a salt and will ionize in aqueous medium.
Answer option: (1) Bubling (H2 gas) (2) disappearanace of solid (Mg metal disapear).
