It depends on which parts of the the tooth are considered, but pH 6.7 and below is an accurate answer in a general sense. In a living organism, a tooth is constantly being demineralised and remineralised and at pH 5.5 the rates of demineralisation and remineralisation are roughly equal. Below pH 5.5 the rate of demineralisation is the greater and the tooth is effectively being corroded away.
Al is resistant to water-corrosion and will only corrode in acid-based conditions (pH<7).
PH levels indicate how acidic or basic a substance is. A pH lower than 7 is acidic and higher than 7 is basic. Since acids dissolve tooth enamel, I would say that substance with lower pHs are more likely to lead to tooth decay.
The pH range for carbonate-bicarbonate buffer is 9,2.
the pH range is around 10
pepsin is activated from pepsinogen in stomach. the pH range for its optimal ativity is at acidic pH between 1.5 to 2. It is also stable upto pH8 and can be inactivated at basic pH from 8.5,
The pH of toothpaste typically ranges from 6 to 9. This range helps to maintain a balanced pH level in the mouth, preventing tooth decay and promoting good oral health.
cavity formation is the word.The tooth tissue starts to decay and corrode .
Al is resistant to water-corrosion and will only corrode in acid-based conditions (pH<7).
The range of pH values is 0 - 14.
PH levels indicate how acidic or basic a substance is. A pH lower than 7 is acidic and higher than 7 is basic. Since acids dissolve tooth enamel, I would say that substance with lower pHs are more likely to lead to tooth decay.
Yes, copper pipes can corrode over time due to various factors such as water quality, pH levels, and exposure to certain chemicals.
No.
The toothpaste is slightly basic.
High range pH refers to the measurement of pH values greater than 7.0, indicating alkaline or basic conditions. This can typically range from pH 8 to pH 14. High range pH is important in applications such as water treatment and regulation of soil pH for agriculture.
The pH range for carbonate-bicarbonate buffer is 9,2.
Acidic solutions attack tooth enamel.
A base typically has a pH range of 8 to 14. pH values above 7 indicate alkalinity, with higher values indicating stronger bases.
