If an acid spills on the desk, we do neutralization with bases,wash it with water, inert absorbent material can be used, then dumped into a special place for toxic and dangerous material
Further explanation
According to Arrhenius, acid is a substance which when dissolved in water releases H⁺ ions.
An HₓY acid in water will ionize:
HₓY (aq) --------> xH⁺ (aq) + Yˣ- (aq)
Example:
HCl -------> H⁺ + Cl⁻
The number of H⁺ ions produced by 1 acid molecule is called valence acid, while residual acid ions are ions formed after the release of H⁺ ions.
Usually, the name acid begins with the word acid followed by the name of the remaining acidic ion
A 2-valent acid based on the Arrhenius concept is an acid molecule that releases 2 H⁺ ions in water.
Example: valentic acid 2
H₂S -----> 2H⁺ + S²⁻
H₂SO₄ ------> 2H⁺ + SO₄²⁻
H₂CO₃ -------> 2H⁺ + CO₃²⁻
H₂C₂O₄ ------> 2H⁺ + C₂O₄²⁻
Whereas bases are compounds that in water release OH- ions
NaOH (aq) -> Na + (aq) + OH- (aq)
The number of OH ions that can be produced by an acid compound is called base valence.
In working in a laboratory, work safety must be a priority. Sometimes it is possible to spill from chemical liquids either on the table or the floor
If there is a liquid chemical spill, then we must know the properties of fluids that have been stated in the MSDS (material safety data sheet).
If liquids such as acids/bases, we do neutralization with bases/acids, (eg spill neutralizers) if we need to see The pH to check the degree of acidity, it is neutral or not, after that we can wash it with water, inert absorbent material can be used, then dumped into a special place for toxic and dangerous material
Keep using personal protective equipment such as gas masks or special gloves
