What causes a substance to expand?
An increase in temperature of the substance causes it to expand.
What causes pH levels to increase?
There are several ways to increase the pH: * Adding a basic or alkali substance, e.g. NaOH, or a basic salt, e.g. CaCO3. * Consumption of the acid in a solution will cause the pH levels to increase (e.g Acid reacting with a metal) * The solution can be absorbing ammonia from the air * Temperature changes can affect pH * Electrolysis of some solutions can produce lowered pH values in the solution
What causes the pH of a solution increase?
adding a base.
What causes pH level to increase in bread?
set it out in the rain.
What is the causes of acid and base?
A substance is classified as an acid or a base, based on the pH of the substance. pH is the rating of a substance compared to water, which is considered neutral. Water has a pH of 7.0. A substance with a pH less than water is considered acid and higher than water is considered a base. The pH of a substance is determined by a mathematical formula that represents the concentration of hydronium ions in a solution.

Which causes pH of a solution to increase?
Adding a base
What causes the pH of a solution increase?
adding a base.
What causes the pH of solution to increase?
Adding a base will make the pH go up (increasing of OH- ions concentration).

What causes the pH of a solution to raise?
An increase in the concentration of OH- ions.
If a substance is added to water and the pH decreases is that substance an acid or a base?
pH of 1 to < 7 indicates an acid pH of >7 to 14 indicates a base pH of 7 indicates water
Which causes the pH of a solution of a solution to increase?
Adding a base

Adding a base will make the pH go up (increasing of OH- ions concentration).
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
