Examining the effect of acidity and alkalinity on bacteria growth inhibition
Acidic and alkaline solutions of a higher concentration were obs
It was also observed that the acidic solution led to a larger inhibition zone compared to the alkali solution of the same concentration.
|Solution used||Diameter of the inhibition zone (mm)|
|Alkali (Sodium Hydroxide)||10||11||18||23|
|Acid (Hydrochloric acid)||12||15||21||29|
Use the graph below to plot the experimental data recorded in the table above.
The bacteria should be destroyed with bleach before it is disposed of. Gloves and protective eyewear must be worn when handling the acid and alkali.
