Answer :The corrected answer is given below;


Weak bases react with <u>water</u> to form the hydroxide ion and the conjugate <u>acid</u> of the base. Concentration in solution does not affect whether an acid or a base is <u>strong </u>or weak.

The strength of an acid or a base is determined by the <u>dissociation constant</u> of the substance in solution.

The acid dissociation constant, <u>Ka</u>, is a quantitative measure of acid strength. A strong acid has a much <u>higher</u> Ka than a weak acid. The Ka of an acid is determined from measured <u>titration</u> values.


Hydrochloric acid and sulfuric acid are <u>completely</u> ionized in solution and are <u>strong</u> acids. Ethanoic acid, which is only about 1 percent ionized, is a <u>weak</u> acid. Magnesium hydroxide and calcium hydroxide are strong <u>base</u>.

completely

Strong

weak

base

Explanation:

Weak bases react with water to form the hydroxide ion and the conjugate acid of the base. Concentration in solution does not affect whether an acid or a base is strong or weak.

The strength of an acid or a base is determined by the dissociation constant (ka /Kb) of the substance in solution.

The acid dissociation constant, Ka, is a quantitative measure of acid strength. A strong acid has a much higher Ka than a weak acid. The Ka of an acid is determined from measured titration values.

Hydrochloric acid and sulfuric acid are completely ionized in solution and are strong acids. Ethanoic acid, which is only about 1 percent ionized, is a weak acid. Magnesium hydroxide and calcium hydroxide are strong base.

What is the pH of a buffer solution upon mixing 15.0 mL of 0.40 M HCl and 20.0 mL of 0.50 M NH? Kb (NH3) = 1.8 x 10 E. 7.00 A. 9
vladimir2022 [97]

<u>Answer:</u> The pH of resulting solution is 9.08

<u>Explanation:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}       ........(1)

  • <u>For HCl:</u>

Molarity of HCl = 0.40 M

Volume of solution = 15.0 mL

Putting values in equation 1, we get:

0.40M=\frac{\text{Moles of HCl}\times 1000}{15.0mL}\\\\\text{Moles of HCl}=0.006mol

  • <u>For ammonia:</u>

Molarity of ammonia = 0.50 M

Volume of solution = 20.0 mL

Putting values in equation 1, we get:

0.50M=\frac{\text{Moles of ammonia}\times 1000}{20.0mL}\\\\\text{Moles of ammonia}=0.01mol

The chemical reaction for hydrochloric acid and ammonia follows the equation:

                  HCl+NH_3\rightarrow NH_4Cl

Initial:          0.006      0.01

Final:             -         0.004              0.006

Volume of solution = 15.0 + 20.0 = 35.0 mL = 0.035 L    (Conversion factor:  1 L = 1000 mL)

  • To calculate the pOH of basic buffer, we use the equation given by Henderson Hasselbalch:

pOH=pK_b+\log(\frac{[salt]}{[base]})

pOH=pK_b+\log(\frac{[NH_4Cl]}{[NH_3]})

We are given:

pK_b = negative logarithm of base dissociation constant of ammonia = -\log (1.8\times 10^{-5})=4.74

[NH_4Cl]=\frac{0.006}{0.035}

[NH_3]=\frac{0.004}{0.035}

pOH = ?

Putting values in above equation, we get:

pOH=4.74+\log(\frac{0.006/0.035}{0.004/0.035})\\\\pOH=4.92

To calculate pH of the solution, we use the equation:

pH+pOH=14\\pH=14-4.92=9.08

Hence, the pH of the solution is 9.08
