Q2. Write true or false:
1. Calcium hydroxide is an alkali.
2. Battery acid is dilute sulphuric acid.
3. Basic soil can be corrected by adding organic acid.
4. A base has a sweet taste.
Answers
Answer:
Calcium, barium, and strontium—all alkaline earth metals—form soluble hydroxides that are strong bases but are less stable than the alkali hydroxides. Of these, calcium hydroxide, Ca(OH)2, commonly known as slaked lime, is the most common.
Battery acid is sulfuric acid that has been diluted with water to attain a 37% concentration level. This particular type of acid is used in sealed lead acid batteries, however, concentration levels differenciate with some brands. ... Sulfuric acid, also known as "oil of vitriol", has a chemical formula of H2SO4 in H2O.
Soil acidity can be corrected easily by liming the soil, or adding basic materials to neutralize the acid present. The most commonly used liming material is agricultural limestone, the most economical and relatively easy to manage source. The limestone is not very water-soluble, making it easy to handle.
Base has taste
Explanation:
There are five universally accepted basic tastes that stimulate and are perceived by our taste buds: sweet, salty, sour, bitter and umami.
