A farmer wants to start growing sweetcorn on his farm. He has found out that sweetcorn grows best in soil with a pH value of approximately 7.5. Explain how he can use the knowledge of acids, alkalis, and neutralisation to find out the pH value of his soil to make sure he gets the best crop possible

The process to use this knowledge is explained as below:

Explanation:

1. Farmer should use an indicator to check the pH value of the soil of the field of the farm.

2. If the field or the farm has alkali soil add acid to reduce the pH value.

3. If the soil of the farm is acidic for the crop add alkali to increase the pH value.

4. It will be a neutralization reaction and changes the pH value of the farm.

5. Weather/leeching into the surrounding soil/plant or animal waste will lead to a change in pH value over time.

6. The pH value will need to be regularly monitored and adjusted.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
