What happens to the pH of an acid when the solution is diluted by a factor of 10?

Diluting an acid decreases the concentration of H+(aq) ions, which increases the pH level of the solution towards 7, making it less acidic.

Explanation:

However, the pH level of an acidic solution cannot become greater than 7, because the water you add to dilute it is not alkaline.

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
