Answer: pOH = 9.88

Explanation:pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

pH=-\log [H^+]

pOH=-\log[OH^-]

Putting in the values:

pOH=-\log[1.3\times 10^{-10}]

pOH=9.88

pH+pOH=9.88

pH=14-9.88=4.12

Thus as pH is less than 7 the solution is acidic and pOH is 9.88.

Question 4
vazorg [7]

Answer:

H(aq) + NO3 (aq) + HF(aq)

Explanation:

In the given mixture of HNO3 (Nitric Acid) and HF (hydrofluoric acid) in water  the major species present are H(aq) + NO3 (aq) + HF(aq).

On the reaction of  HNO3 (Nitric Acid) and HF (hydrofluoric acid) in water  , it will give a polar solution and will form a homogenous mixture.

Hence, the correct answer is "H(aq) + NO3 (aq) + HF(aq)".
