What is the pH range of a strongly acidic solution?
7-8
0-3
12-14
10-11
0-3
A strongly acidic solution has a very low pH range, specifically between 0 and 3. This indicates a high concentration of hydronium ions (H3тАЛO+) or hydrogen ions (H+) in the aqueous solution.
A strongly acidic solution has a very low pH range, specifically between 0 and 3. This indicates a high concentration of hydronium ions (H3тАЛO+) or hydrogen ions (H+) in the aqueous solution.
Stomach acid (gastric juice) has a pH of about 1.5 to 2, which helps digest food and kill bacteria, representing a strongly acidic environment.
0 to 3 is strongly acidic, 7 is pure heaven (neutral), 11 to 14 is basic/alkaline!
pH=тИТlog10тАЛ[H+] тАФ Definition of pH
[H+][OHтИТ]=10тИТ14 тАФ Ionic product of water at 25┬░C
The pH scale ranges from 0 to 14, measuring the logarithmic concentration of hydrogen ions in moles per litre: pH=тИТlog10тАЛ[H+]. Strongly acidic solutions have high [H+] values (greater than 10тИТ3┬аM), which place them at the extreme lower end of the pH spectrum (0 to 3), turning universal indicator deep red or pink.
Strong acids dissociate almost completely in water, releasing a high concentration of H+ ions.
The pH scale is logarithmic; a decrease of 1 pH unit represents a tenfold increase in hydrogen ion concentration.
Option B (0-3) represents the correct range for strongly acidic solutions.
Enables rapid identification of acid strength in chemical analyses
pH meter readings can be affected by high ionic strength or extreme temperatures
Industrial chemical synthesis and wastewater neutralization
Biological research and pharmaceutical formulation
Option A (7-8) represents neutral to weakly basic solutions.
Option C (12-14) represents strongly alkaline (basic) solutions.
Option D (10-11) represents moderately alkaline solutions.
B is correct тАФ The pH range of a strongly acidic solution is 0-3.
Remember that lower pH numbers mean higher acidity, and because the scale is logarithmic, a pH of 1 is 10 times more acidic than a pH of 2.
