All substances have different pH levels. The pH level is just a measure of the acidity of a substance. A pH level of 7 would indicate that the substance in question is neither acidic or basic, water is commonly given as having a pH level of 7, (though tap water is often slightly lower due to the chlorine content). The scientific answer to your question would be that the pH level would be different due to the variance in the number of free hydrogen atoms or protons, in the different cosmetics.
There is no one answer to this. Every location will have a different pH level. Indeed, different parts of the same field might have different pH levels.
The general PH level for foods that cause heartburn is around a pH level of about 4. It depends on the status of your stomach before getting heartburn (e.g. whether your stomach is resistant to acidic foods initially)
The pH level of different plants can be sometimes found in a pH tester. I have a chart that has probably a hundred different plants with all different suggested pH's. You can go to any search engine and type in "What is the suggest pH for [plant so and so]" and you'll find all you need about the plant's suggested pH. I hope this helped.
There are different types of window cleaner with different pH levels. A typical window cleaner would have a pH of between 10-14.
Ph levels affect the balance of things. If an ecosystems Ph level is off, it can cause a surplus in bacterial growth.
In order to find the pH you will need to test the soil. Different factors will effect the pH and different plants grow better at a different pH. I heard its ph level is "6" the ideal fertilizer for gardening. Its neutral. The ph levels go from 0-11 :)

Apples have a pH level of 3. Also, soda has a pH level of 4, and vinegar's pH level is 2.5.
Bleach has a pH level of 13. Distilled water has a pH of 7 while the pH of black coffee is 5 and the pH of lemon juice is 2.
The pH level of an orange is 4.3.
pH balance is important as if it is too low, it can cause severe damage to internal organs which could, in some cases, cause death if the substance has a high acidity level. Heart-Burn is in reference to high acidity levels in the stomach. The pH level of the acid is reduced and almost neutralized by using an alkali to increase the pH level and maintaining a neutral one thus, reducing pain.
PH level of a country?
