The number 3,072 has 4 significant figures.
The activity of salivary amylase is highest around neutral pH, typically between pH 6.5 to 7.5. Any significant deviation from this pH range can lead to a decrease in enzyme activity.
The difference in strength between pH 9 and pH 4 is significant. As pH is measured on a logarithmic scale, each whole number change represents a 10-fold difference in acidity or basicity. In this case, pH 9 is 100,000 times stronger in basicity compared to pH 4.
This is a jet fuel so it may contain water so it does not have a pH
The pH of the body can be altered in various areas including the blood, stomach, urine, and skin. Imbalances in pH levels in these areas can have significant impacts on bodily functions and overall health.
The pH of beeswax is typically neutral, around 7.0. Beeswax is composed primarily of fatty acids and hydrocarbons, which do not exhibit significant acidity or alkalinity.
It is equally wrong to record too many digits, since this implies greater ... Thus, significant figures are those digits that give meaningful but not ... 3.43+8.6=12.0 ... 8 x 10-4 we can calculate the pH from the definition of quantity.
pOH = -log [OH-], so pH = -log 9.0x10^-7pOH = 6.05 = 6.1 (to 2 significant figures)

The pH scale shows the relative acidity (H+ ions) and basicity (OH- ions) of a sample. A pH of <7.0 is acidic; a 7.0 pH is neutral and, one with a pH >7.0 is basic.
The Ph. of all human blood is the same. Different races of people do not possess different Ph. balances of their blood.

Environmental pH is important for organisms, especially aquatic species, because it influences many physiological processes such as enzyme activity, ion regulation, and metabolism. Slight changes in pH can have significant impacts on organism health and survival. Aquatic species, in particular, are more sensitive to pH fluctuations because they live in an environment where pH can vary rapidly and significantly.
