An acid solution of pH =6 is diluted 1000 times, the pH of the final solution becomes

Step-by-step solution

pH =6 [ H ⁺ ]=10⁻⁶ M After dilution [ H ⁺ ]= 10⁻⁶ 1000 =10⁻⁹ M [ H ⁺ ] from H ₂ O cannot be neglected. Total [ H ⁺ ]=10⁻⁹+10⁻⁷ aligned &=10⁻⁷ (10⁻²+1 ) &=10⁻⁷(1.01) pH &=- (1.01 10⁻⁷ ) &=7-0.0043 &=6.9957 aligned
