Question 5 a solution is prepared at 25°c that is initially 0.35m in chlorous acid hclo2, a weak acid with =ka×1.110−2, and 0.29m in sodium chlorite naclo2. calculate the ph of the solution. round your answer to 2 decimal places.

Answer : The pH of the solution is, 1.88

Explanation : Given,

Concentration of = 0.35 M

Concentration of = 0.29 M

First we have to calculate the value of .

The expression used for the calculation of is,

Now put the value of in this expression, we get:

Now we have to calculate the pH of the solution.

Using Henderson Hesselbach equation :

Now put all the given values in this expression, we get:

Therefore, the pH of the solution is, 1.88

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
