What is the pH of 12.5 M HCL Solution? Calculate the pH of 12.5 …
WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebOct 22, 2024 · Thus, pH = 14 - 4.74 = 9.26. CASE TWO: after addition of 12.5 mL of HBr. Number of moles of H^+ present= (The initial concentration of H^+) × ( addition of 12.5 mL of HBr) = 0.220 × 12.5 × 10^-3= 2.7 × 1O^-3 mol. Number of moles of C5H5N present = 25 × 10^-3 × 0.220. = 5.5 × 10^-3 mol. Therefore at equilibrium; golf cart rentals seagrove beach fl
