A) 7.00
B) 6.68
C) 7.63
D) 6.00
E) zero
Correct Answer: B
Solution :
\[p{{K}_{w}}=13.36\] (temperature\[=50{}^\circ C\]) pH of water = ? (temperature\[=50{}^\circ C\]) \[p{{K}_{w}}=pH+pOH\] (for pure water \[pH=pOH\]) \[\therefore \] \[p{{K}_{w}}=2pH\] By putting the values \[13.36=2\times pH\] \[pH=\frac{13.36}{2}=6.68\]You need to login to perform this action.
