4.When milk is turned into curd then its pH value will decrease due to the production of lactic acid in curd which is acidic in nature. ... It turns sour and the ph value decreases from 6....
5. By adding a very small amount of baking soda to fresh milk, the milkman keeps the milk unspoiled for little more time than usual time. c) As baking soda is added, it turned into a base. ... Hence this milk takes a long time to set as a curd.....As this milk is slightly more alkaline than other, therefore, acid produced to set into curd will be neutralized by baking soda added by milkman. Hence, this milk takes a longer time to set as curd....
6. Toothpaste is alkaline in nature. The action of bacteria occurs in acidic medium in the mouth and hence toothpaste neutralises the acid and doesn't allow tooth decay to occur.As tooth surface is made up of calcium crystals these acids destroy them. Hence we get cavities.....:)

Q. (a) Mention the pH range within which our body works. Explain how a...
(a) pH range of our body and how antacids work:
- The pH range within which our body works is between 7.35 to 7.45.
- When the pH level of the stomach becomes too acidic, it causes acidity and heartburn. Antacids are medicines that neutralize the acid in the stomach and give relief from acidity.
- Antacids contain bases such as magnesium hydroxide, aluminum hydroxide, and calcium carbonate. These bases react with the stomach acid to form salt and water, which neutralizes the acid. This helps in reducing the symptoms of acidity.
- One such antacid is Tums, which contains calcium carbonate.
(b) pH change of milk as it turns into curd:
- The pH of fresh milk is 6, which is slightly acidic.
- When milk turns into curd, lactic acid bacteria convert lactose (milk sugar) into lactic acid. This lactic acid lowers the pH of the milk.
- As the lactic acid accumulates, the pH of the milk drops to around 4.5, which is acidic.
(c) Effect of baking soda on the curdling of milk:
- Baking soda is a base and can neutralize the acidity of the milk.
- When a milkman adds a very small amount of baking soda to fresh milk, the milk becomes less acidic and it takes a longer time to set as curd.
- This is because the lactic acid bacteria that are responsible for curdling the milk require an acidic environment to grow and multiply. When the acidity of the milk is reduced by baking soda, the growth of lactic acid bacteria is slowed down, which delays the curdling process.
(d) Nature of toothpastes and their role in preventing tooth decay:
- Toothpastes are generally basic in nature and contain fluoride, abrasives, detergents, and flavoring agents.
- Fluoride is an important ingredient in toothpaste as it helps in strengthening the enamel of the teeth and prevents tooth decay.
- Abrasives in toothpaste, such as calcium carbonate and silica, help in removing the plaque and stains from the teeth.
- Detergents such as sodium lauryl sulfate help in foaming and spreading the toothpaste in the mouth.
- Flavoring agents in toothpaste help in improving the taste and smell of the toothpaste, making it more pleasant to use.
- Toothpastes prevent tooth decay by removing the plaque and bacteria from the teeth, strengthening the enamel, and making the teeth more resistant to acid attacks.
