These molecules haven't an effect on pH.
If the salt is insoluble, any ions in water and the measured pH is the pH of water.
It is a polymer and insoluble in water so the pH of water should be 7
Nylon is a polymer insoluble in water so it can not change the pH value of water which is 7.
Because it is insoluble in water.
Iron(II) sulfide is insoluble in water.
Since it is almost insoluble in water (< 13 mg/L) there is no pH influence on the normal water pH = 7. Besides: concentration (not mentioned) is of big influence on pH!
No, ozone does not affect PH of water. However as ozone is a powerful oxidizer it can oxidize compounds in the water that may indirectly change the PH of the water.
Adding water will affect the pH. Adding water will shift the pH towards the neutral mark. In the case of an alkaline solution, there will be a decrease in pH.
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
A base or alkali affects the pH water by increasing it.
Fertilizers contain nitrogen and phosphorus which can affect the pH of water ways. A pH of 7 is neutral. When water pH is raised above this, it can have harmful affects on the waterway, causing nutrient or water pollution.
