A solution with a pH value which is less than 7 is acidic. The acids which react with metals usually have quite a low pH, of either 3 or less. Some metals react with acids and when they do the ...

We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction ...

Fuel cells that react liquid sodium metal with air could be the power source required to give electric airplanes much longer ranges, a new paper has proposed. The idea has yet to leave the laboratory ...
