3 days ago · The pH pH range for water varies from the surface of earth to ground. Mostly the water is found in the pH pH range of 6.5 − 8.5 6.5 − 8.5 but if the water is pure then it has the pH pH value 7 because it is neither acidic nor basic, it is neutral in nature. The pH pH value represents the power of hydrogen.
5 days ago · B) Milk of magnesia Milk of magnesia is used to reduce the oil in our face. It can also help in reducing acne. It is used to set our makeup so that it lasts longer. Hence, it is inappropriate to use it on the stung area. Therefore, this option is incorrect. C) Baking soda
5 days ago · (a) The pH of milk is around 6. At this pH, milk soon becomes spoiled and becomes undrinkable. So it cannot be kept for a longer time. To prevent the spoilage of milk, the milkman adds a very small amount of baking soda to fresh milk. Baking soda is sodium bicarbonate. It is basic in nature. Addition of baking soda increases the pH of milk from 6.

3 days ago · Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digest solid food. [1] Immune factors and immune-modulating components in milk contribute to milk immunity.
3 days ago · Afterward, these bacteria start to multiply and convert milk into curd. This whole chemical process is known as fermentation. -The formation of lactic acid starts due to fermentation, which is acidic. The pH value of curd is $4.5 - 5.5$. So, the pH value of curd will decrease. Note: The pH scale was discovered by Soren Sorensen.
4 days ago · If a solution is an acid, then it will have a pH below 7, and if the solution is a base, it will have a pH above 7 since the pH value is determined by the concentration of H+ and OH- ions. The independent variable, the one that is intentionally manipulated, is: the physical properties. The dependent variable, the one that you measure the ...
