During lab, you measured the heat of reaction by mixing solutions of FeCl3 and NaOH. (a) Write the balanced net precipitation reaction that occurred. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.)

The balanced net precipitation reaction:

Explanation:

When ferric chloride reacts with sodium hydroxide solution it gives precipitate of ferric hydroxide and  solution of sodium chloride.

Removing the common ion on both sides:

The balanced net precipitation reaction:

- decrease the number of plants and animals living in the water.
