The equation 4HNO3 + 3Ti -> 3Ti(NO3)4 + 4H2O

  1. Detailed information about the equation 4HNO3 + 3Ti -> 3Ti(NO3)4 + 4H2O
    The above chemical equation represents the reaction process between nitric acid and titanium, resulting in titanium nitrate and water. According to the equation, every 4 moles of nitric acid will react with 3 moles of titanium to produce 3 moles of titanium nitrate and 4 moles of water.

  2. Reaction conditions
    This reaction occurs in an excess acid environment and at high temperatures. Nitrogen oxide (NO) gas is then released, giving the surrounding environment a sharp smell.

  3. Reaction process

    • Step 1: Nitric acid reacts with titanium to produce titanium nitrate and hydrogen gas.
    • Step 2: Hydrogen gas reacts with nitric acid to produce water and nitrogen oxide gas.

  4. Phenomena occur
    When the reaction occurs, we can see the phenomenon of gas escape, accompanied by the smell of nitrogen oxide. On the other hand, the initial solution changes from a faint orange-yellow to clear due to the decreasing concentration of nitric acid.
