Question

Baking soda turns:
A.Turmeric to red.
B.Purple-Cabbage juice to green.
C.Red litmus to blue.
d.All of the above.

Answer 1

Hint: We know that the baking soda is highly used in cooking due to its ability to release carbon dioxide when it reacts with water. Hence this levitates the substance and gives a porous structure. Baking soda has many other uses. It is used to relieve heartburn which is also known as acid reflux. This is due to its mildly basic nature.

Complete answer:
As we know that baking soda is used in making baking powder which is a mixture of baking soda and a mild acid such as tartaric acid. This baking powder is used as a leavening agent which is also a chemical used in batter and dough that releases a gas and makes dough rise and expand in baking bread, cakes, cookies, pancakes, patties etc. When baking powder mixes with water present in cake dough, then sodium bicarbonate reacts with tartaric acid to produce carbon dioxide gas.
Baking soda solution can be used as a mouthwash. Baking soda can relieve the pain of canker sores which are painful ulcers in the mouth. Baking soda is also used to whiten the teeth and also as a natural deodorizer. Similarly turmeric red litmus to blue and purple cabbage (Liquid) to green are all can be done by baking soda since its nature is basic and all the given options are acting as indicators(natural indicators).
Therefore the correct answer is option D.

Note:
Remember that the solution of sodium hydroxide reacts with lime water or a solution containing carbon dioxide dissolved in water then it results in the formation of baking soda or sodium hydrogen carbonate or sodium bicarbonate.
