Which graph represents a titration between NaOH times aq and HCl times aq ?
Answer
A
Image with description A schematic of a S-curve graph represents a titration curve with the X-axis labeled 'Volume of Acid Added (mL)' ranging from 0 to 60 with intervals of 10 mL, and the Y-axis labeled 'pH' ranging from 0 to 12 with intervals of 2 pH mL. The curve starts from the point (0, 11), decreases gradually until it reaches (50, 8), and then falls sharply from (50, 8) to (50, 4), indicating the point of steepest decline.
B
Image with description A schematic of a S-curve graph represents a titration curve with the X-axis labeled 'Volume of Base Added (mL)' ranging from 0 to 20 with intervals of 5 mL, and the Y-axis labeled 'pH' ranging from 0 to 14 with intervals of 2 pH mL. The curve starts at the point (0, 4), rises steadily to (10, 8), then sharply increases from (10, 8) to (10, 12), before leveling off around (15, 12).
C
Image with description A schematic of a S-curve graph represents a titration curve with the X-axis labeled 'Volume of Base Added (mL)' ranging from 0 to 50 with intervals of 10 mL, and the Y-axis labeled 'pH' ranging from 0 to 14 with intervals of 2 pH mL. The curve starts at the point (0, 1), increases gradually to (10, 1), then sharply rises till (15,6) and form a horizontal line till (25,6). A sharp increase in pH is observed from (25, 6) to (35, 13), and finally levelling off around (40, 14).
D
Image with description A schematic of a S-curve representing a titration graph. The X-axis represents the 'Volume of Base Added (mL)' ranging from 0 to 100 with intervals of 20 mL. The Y-axis represents pH, ranging from 0 to 14 in multiples of 2. The curve starts from the point (0, 1) to (40, 3). A vertically straight line is observed from (40, 3) to (40, 11). From there onwards to the end, the line is almost horizontal, forming an 'S' shape.
