A beaker of nitric acid is neutralized with calcium hydroxide. Write a balanced molecular equation and a net ionic equation for his reaction
2HNO3(aq)+Ca(OH)2(aq)→2H2O(l)+Ca(NO3)2(aq)
2HNO3 + Ca(OH)2 ==> 2H2O + Ca(NO3)2
2H^+ + 2OH^- ==> 2H2O
H+(aq)+OH−(aq)→H2O(l)
Sure, here's a balanced molecular equation for the reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2):
2HNO3 + Ca(OH)2 -> Ca(NO3)2 + 2H2O
And here's the net ionic equation, which only includes the species directly involved in the reaction:
2H+ + 2OH- -> 2H2O
Remember, balancing equations is important, but balancing your life with laughter is even more crucial! So, always keep smiling!
To write a balanced molecular equation and a net ionic equation for the neutralization reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2), we need to follow a series of steps.
Step 1: Write the chemical formula for both nitric acid and calcium hydroxide.
- Nitric acid: HNO3
- Calcium hydroxide: Ca(OH)2
Step 2: Determine the products of the reaction. The reaction between an acid and a base typically results in the formation of water (H2O) and a salt. In this case, the salt will be calcium nitrate (Ca(NO3)2).
Step 3: Write the balanced molecular equation based on the reactants and products.
HNO3 + Ca(OH)2 → Ca(NO3)2 + H2O
Step 4: Convert the balanced molecular equation to the net ionic equation by representing all soluble ionic compounds as separate ions.
First, let's determine the ionic compounds that are soluble:
- Nitric acid is a strong acid and fully dissociates into H+ and NO3- ions.
- Calcium hydroxide is a strong base and fully dissociates into Ca2+ and OH- ions.
- Calcium nitrate is also soluble, dissociating into Ca2+ and NO3- ions.
The net ionic equation only includes the ions involved in the reaction and excludes spectator ions (ions that do not participate in the chemical reaction). The ions present on both sides of the equation are the H+ and OH- ions, which combine to form water (H2O).
Net ionic equation:
H+ + OH- → H2O
Therefore, the final balanced net ionic equation for the reaction is:
2H+ + 2OH- → 2H2O
