Balanced equation
Solution
Chemical equations can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
Sodium hydroxide reacts with a solution of iron (III)
nitrate to create a solid of iron (III) hydroxide in a solution of
sodium nitrate.
We determine the chemical formula of each compound then we balance the chemical equation
Sodium hydroxide = NaOH
Iron (III)nitrate = Fe(NO₃)₃
Iron (III) hydroxide = Fe(OH)₃
Sodium nitrate = NaNO₃
Reaction
NaOH + Fe(NO₃)₃⇒ Fe(OH)₃ + NaNO₃
Give a coefficient(most complex compound = 1)
aNaOH + Fe(NO₃)₃⇒ bFe(OH)₃ + cNaNO₃
Fe, left = 1, right=b⇒b=1
N, left=3, right=c⇒c=3
O, left=a+9, right=3b+3c⇒a+9=3b+3c⇒a+9=3.1+3.3⇒a+9=12⇒a=3
The equation becomes :
<em>3NaOH + Fe(NO₃)₃⇒ Fe(OH)₃ + 3NaNO₃</em>
