1.What is a neutralisation reaction ?
2.What is an indicator ?
3.How is acidic soil treated ?
please answer these questions. And please give the right answer.
Answers
Answer:
1. when acid reacts with base it forms salt and water, and this reaction is called as neutralisation reaction.
2.an indicator tells us that the solution is either acidic or basic or neutral.
3.by the addition of lime/limestone (calcium carbonate) and similar compounds that have been ground fine for use.

Answer:
1. A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.
2.Chemical indicator, any substance that gives a visible sign, usually by a colour change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. An example is the substance called methyl yellow, which imparts a yellow colour to an alkaline solution.
Examples-
- Universal indicator.
- Litmus.
- Phenolphthalein.
- Methyl orange.
- Bromothymol blue.
3.Soil acidity can be treated and the pH of the soil increased by the addition of lime/limestone (calcium carbonate) and similar compounds that have been ground fine for use. Types of lime-like amendments include: Dolomitic limestone.
