explain the experimental procedure that explains the chemical reaction between metal and an acid
IN EXPERIMENT PROCESS
Answers
Explanation:
Aim:To show the reaction between an acid and a metal
Things needed:granulated zinc metal, a test tube and 5mL of dil. sulphuric acid and a delivery tube .
steps: 1.Take about 5mL of dil.sulphuric acid in a test tube and as a few pieces of zinc granules to it
2. Connect a delivery tube with the test tube so that it passes to the soap solution.
Observation:We will observe that hydrogen gas bubbles are formed in the solution and we can test whether the gas liberated is either hydrogen by passing it through a soap solution and the bringing a burning candle if the candle burns with a pop sound then it is hydrogen gas .
From this we can conclude that
Acid + Metal -----> Salt + Hydrogen gas
and the reaction is
Zn + H2SO4 ----> ZnSO4+ H2
Answer:
Acids give hydrogen gas along with respective salt when they react with metal. The presence of hydrogen gas is confirmed by a pop sound that is produced by hydrogen gas when it comes in contact with fire. Hydrogen gas and zinc chloride are formed when hydrochloric acid reacts with zinc metal.
