Compared with a basic solution at ph 9

WebThe pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral. WebNov 21, 2014 · You can't use pH to compare the acidities in different solvents because the neutral pH is different for each solvent. For example, the concentration of hydrogen ions in pure ethanol is about 1.58 × 10-10 …

This answer is: Study guides. WebpH = −log [H+] pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is …

WebMar 16, 2024 · The solution is acidic if its pH is less than 7. If the pH is higher, the solution is basic (also referred to as alkaline). Solutions with a pH that is equal to 7 are neutral. Apart from the mathematical way of … WebDec 27, 2024 · A solution with a pH of 11 is more basic than a solution with a pH of 8. This is because a pH value greater than 7 indicates a basic solution. As the pH value increases from 7 to 14, there is an increase in the concentration of OH-, which increases the strength of the solution.

WebFor bases we can state the folllowing: The higher the pH of a substance, the more basic it is. Here is a summary: The closer to pH 1, the more strongly acidic the solution; The closer to pH 14, the more strongly basic the solution; and; pH 7 is a neutral substance. We have learnt that the pH value of a substance tells us if it is an acid or a base.
