Question

The ph of a neutral solution at 50 degree celsius is

Answer 1

Answer:

6

Explanation:

You can check this as if you find the total concentration of H+ ions and OH− ions, you will find that they both equal 10−6.

Answer 2

The pH of a neutral solution at 50 degrees Celsius is 6.63

Ionic product of water is $K_w=10^{-13.26}$

$K_w=[H^{+}][OH^{-}]$

We know that, $[H^{+}]=[OH^{-}]$

Therefore,

$[H^{+}]^{2}=K_w$

$[H^{+}]=\sqrt[]{K_w}$

       $=\sqrt[]{10^{-13.26}}$

       $=2.344\times 10^{-7}$

The pH is given by,

$pH=-log([H^{+}])$

     $=-log(2.344\times 10^{-7})$

     $=6.628$

∴ pH = 6.63
