Answer:
C. NaOH(s) + HCl(aaq) rightarrow NaCl(s) + H2O(aq)
Explanation:
A neutralization reaction may be defined as the reaction where an acid when it reacts with some base, the products formed are a salt and water.
Simply, we can write,
acid + base ---> salt + water
Here in option (C),
NaOH is sodium hydroxide is an base
HCl is hydrochloric acid
NaCl is sodium chloride and is the common salt
H20 is water
So, option C). NaOH(s) + HCl(aaq) -----> NaCl(s) + H2O(aq) is a neutralization reaction.
B) When describing very dilute solutions.
Explanation:
The most appropriate time to use ppm is when describing dilute concentrations of solutes in solutions. It is used mostly to determine trace amount of elements in water and soils.
- The part per million ppm is the amount of miligram of a solute in a liter of solution.
- It is similar to percentage.
- Minute and trace concentrations are very difficult to work with.
- Using parts per million, they become better appreciated and easy to use.
