\huge \mathsf \purple{Question}

how does fertilizer affect the quality of crops?

\huge \mathsf \pink{Answer}

The role of fertilizers in food production is usually underestimated. Fertilizers are food for plants.

Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops.

<h3>Put simply – we use fertilizer to: </h3>

  • Provide nutrients not available in the soil.
  • Replace nutrients removed at harvest.
  • Balance nutrients for better. producequality and higher yield.

Answer:

pH = 3.215

Explanation:

From the given information;

Using the equation for the dilution of  a stock solution:

Since moles of C5H5N = moles of HNO3

Then:

M_{C_5H_5N}\times V_{C_5H_5N}= M_{HNO_3}\times V_{HNO_3}

0.0750 M \times 2.65 L = 0.407 M \times V_{HNO_3}

V_{HNO_3}= \dfrac{0.0750 M \times 2.65 L}{0.407 M}

V_{HNO_3}=488.33 \ mL

The reaction between C5H5NH and H2O is as follows:

C_5H_5N^+H + H_2O ⇄ C_5H_5N + H_3O^+

Molarity  \ of \ C_5H_5N^+H = \dfrac{moles}{addition \ of\  the\  total\ volume}

Molarity  \ of \ C_5H_5N^+H = \dfrac{0.0750 \ M \times 2.65 \ L}{2.65 \ L + 0.48833 \ L}

Molarity  \ of \ C_5H_5N^+H = \dfrac{0.19875 \ ML}{3.13833 L }

= \ 0.06333\ M

Now, the next step is to draw out the I.C.E table.

    C_5H_5N^+H + H_2O ⇄ C_5H_5N + H_3O^+

I       0.06333                      0          0

C        - x                               x          x  

E      0.06333 -x                   x          x

K_a  = \dfrac{10^{-14}}{1.7 \times 10^{-19}} \\ \\  K_a = 5.8824 \times 10^{-6}

K_a = \dfrac{[C_5H_5N][H_3O^+] }{[C_5H_5N^+H] }  \\ \\  5.8824 \times 10^{-6} = \dfrac{x^2}{0.06333 - x}

Assuming x < 0.06333

x^2 = 5.8824 \times 10^{-6} \times 0.06333

Then

x^2 = 3.72532392 \times 10^{-7} \\ \\ x= \sqrt{3.72532392 \times 10^{-7}} \\ \\  x = 6.1035 \times 10^{-4} \ M

[H_3O^+] =  x = 6.1035 \times 10^{-4} \ M  \\ \\  pH = -log (6.1035 \times 10^{-4}) \\ \\ \mathbf{\\ pH = 3.215}
