Question

20 mL of 0.5 N HCl and 35 mL of 0.1 N NaOH are mixed. The resulting solution will (A) be neutral (B) be basic (C) turn phenolphthalein solution pink (D) turn methyl orange red

For 20 mL of 0.5 text N text HCl N1V1=0.5× 20=10 For 35 mL of 0.1 text NaOH N2V2=0.1× 35=3.5 ∵ N1V1>N2V2 ∴ Solution will be acidic in nature. Due to acidic nature of solution, the colour of phenolphthatein becomes pink.

Q. 20 mL of 0.5 N $H Cl$ and 35 mL of 0.1 N $N a O H$ are mixed. The resulting solution will

be neutral

be basic

turn phenolphthalein solution pink

turn methyl orange red

For 20 mL of $0.5 N H Cl$ $N_{1} V_{1} = 0.5 \times 20 = 10$ For 35 mL of $0.1 N a O H$ $N_{2} V_{2} = 0.1 \times 35 = 3.5$ $∵$ $N_{1} V_{1} > N_{2} V_{2}$ $∴$ Solution will be acidic in nature. Due to acidic nature of solution, the colour of phenolphthatein becomes pink.
