Explanation:
1)The word acid comes from the Latin word acere, which means "sour." Most acids taste sour, i.e. vinegar, sour milk, lemon juice.
2)Acids And Bases
Curd, lemon juice, orange juice and vinegar taste sour. These substances taste sour because they contain acids. The chemical nature of such substances is acidic. The word acid comes from the Latin word acere which means sour.
3)The litmus paper is the most commonly used indicator in laboratory
Litmus paper is made by the chemical substance called litmus that is extracted from lichens.
The solution of litmus contains some dyes which are absorbed on the filter paper and by this way litmus papers are made.
4)soory but I am not knowing 4th answer....
5)deoxyribonucleic acid
Each cell in our body contains an acid, the deoxyribonucleic acid or DNA.
6)A litmus paper is an acid base indicator. If it turns the red paper in to blue the solution is acidic. In the above question the litmus paper is red and if it dipped in solution and it remains red it means the solution is acidic as it do not have any effect on litmus paper
7)The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes
8)Organic matter causes soil to clump and form soil aggregates, which improves soil structure. With better soil structure, permeability (infiltration of water through the soil) improves, in turn improving the soil's ability to take up and hold water. This property of organic matter is not widely known.
9)The most common way to raise the pH of soil is to add pulverized limestone to the soil. Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate.
10)Soap solution is basic. We can know by comparing its characteristics with that of a base. Soap is bitter in taste. Base have a property that they are soapy to touch
