Calculate the pH of a solution with an H+ ion concentration of 9.36 x 10-3 M ?

mel-nik [20]

Answer:

The answer is 2.03

Explanation:

The pH of a solution can be found by using the formula

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

where H+ is the Hydrogen ion concentration

From the question we have

$pH = - log(9.36 \times {10}^{ - 3} ) \\ = 2.02872415...$

We have the final answer as

Ppredict the identity of the precipitate in the below reaction: BaCl2(aq) + K2SO4(aq) →

Annette [7]

Answer: The precipitate formed is $BaSO_4$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid or precipitated form are represented by (s) after their chemical formulas.

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced chemical equation is:

$K_2SO_4(aq)+BaCl_2(aq)\rightarrow BaSO_4(s)+2KCl(aq)$
