Question

b) suppose maya spilled hydrosulphuric acid onto the counter! using your knowledge of chemical reactions, suggest how the teacher could neutralize the effects of this chemical. the teacher has either water or hydrochloric acid or sodium bicarbonate available for this student. in your response, you must specify a chemical she may use, and what products will be formed in the reaction. ensure that you provide a balanced chemical equation and that you can explain what is happening.

skeletal equation:
balanced chemical equation:

Explanation:

Step1: Select neutralizing agent

Sodium bicarbonate ($NaHCO_3$) can react with hydrosulphuric acid ($H_2S$) to neutralize it as it is a base - like compound. Water will not neutralize the acid and hydrochloric acid is another acid.

Step2: Write skeletal equation

$H_2S+NaHCO_3
ightarrow$ products

Step3: Determine products and balance

The reaction between hydrosulphuric acid and sodium bicarbonate produces sodium hydrogen sulphide ($NaHS$), carbon dioxide ($CO_2$) and water ($H_2O$).
The balanced chemical equation is $H_2S + NaHCO_3=NaHS+CO_2 + H_2O$

Answer:

The teacher should use sodium bicarbonate. The products formed are sodium hydrogen sulphide, carbon dioxide and water. The balanced chemical equation is $H_2S + NaHCO_3=NaHS+CO_2 + H_2O$
