Solid therefore can be contained itself and can absorb acid and base solutions.When cleaning the spill of an unknown liquid (either acidic or basic), it is important to carefully chose a suitable chemical in order to minimise any damage. One such chemical that may be used is Sodium Hydrogen Carbonate (NaHCO3). This chemical is particularly useful in cleaning spills of acids and bases for multiple reasons.
Its ion HCO3- is amphiprotic, meaning it can donate or accept a proton, which is ideal for when the nature (acidity or basicity) of the spill is unknown, as it can neutralise either.
With the spill of the acid HCl
HCl + NaHCO3 <-> H2O + CO2 + NaCl
And in the spill of the base NaOH
NaHCO3 + NaOH <-> Na2CO3 +H2O
as seen in the above equations NaHCO3 neutralises both acids and bases.
NaHCO3 is a solid chemical, and can thus be contained easily.
It is non-toxic, and is thus safe to handle in school labs
Thus it can be seen that NaHCO3 is a suitable chemical to clean up acid and base spills
Is this even close to right?
Also:
You might want to consider: the fizzing can indicate the extent of completion allowing safety, heat of neutralisation is low hence less damage to surroundings since weak base.
I would say 4/5 (1-equations, 1- amphiprotic 1- evaluation 1-Property but the part of heat of neutralisation was important so you lost 1 there)
