Sulphuric Acid (H2SO4) okay.so i have my answers down but im still getting the hang of it.its another physical or chemical changethanks again ! Sometimes, the crystal-like precipitates are later separated from the copper and used in pieces of fractal artwork. I am in 11th grade. Copper is above silver in the reactivity series of metals, meaning it is more reactive than silver. The precipitate from the hydrochloric acid and silver nitrate solution went through chemical change because the precipitate cannot change back to the original liquid form. I am in 11th grade. CapitalEquipment Characteristic that cannot be observed without altering the substance. The above reaction shows that when copper reacts with silver nitrate, copper nitrate and silver are produced as the desired products.
