The correct answer is: B. Hydroxides of magnesium and aluminium
Antacid tablets are used to neutralize stomach acid. They work by reacting with the acid to form a salt and water. The most common types of antacids are:
- Magnesium hydroxide (Milk of Magnesia)
- Aluminum hydroxide (Amphojel)
- Sodium bicarbonate (baking soda)
These antacids can be used to treat heartburn, indigestion, and upset stomach. They can also be used to treat acid reflux disease.
Magnesium hydroxide and
aluminum hydroxide are the most common ingredients in antacid tablets. They are both effective at neutralizing stomach acid. However, they can cause side effects, such as diarrhea and constipation.Sodium bicarbonate is a less common ingredient in antacid tablets. It is also effective at neutralizing stomach acid, but it can cause side effects, such as bloating and gas.
Antacid tablets should be taken with food or milk to prevent stomach upset. They should not be taken for more than two weeks without talking to a doctor.
Here is a brief explanation of each option:
- Option A: Hydroxides of sodium, magnesium and aluminium. This is not a correct answer because antacid tablets do not contain sodium hydroxide.
- Option B: Hydroxides of magnesium and aluminium. This is the correct answer because antacid tablets typically contain magnesium hydroxide and aluminum hydroxide.
- Option C: Hydroxides of sodium and aluminium. This is not a correct answer because antacid tablets do not contain sodium hydroxide.
- Option D: Hydroxides of magnesium and sodium. This is not a correct answer because antacid tablets do not contain sodium hydroxide.
