How does a solution with a pH of 6 compare to a solution with a pH of 9?

pH 6 is a very weak acid and pH 9 is an alkaline


Aqueous solution with a pH of 9 an acid or a base?

The half way point (that is neutral pH) is 7. Above 7 is basic, and below 7 is acidic. Therefore a pH of 9 is a little basic.


If a solution has a pH of 9 is it an acid or base?

It is a base. Acids = 1 to 7, bases = 7 to 14.


Describe a solution with a pH of 9?

This solution is basic, since it has very little dissolved Hydronium ion. (It has exactly 10-9 hydronium ions per Liter, which is very few. Less hydronium ions means less acidity.) Remember too that a solution with pH > 7 is basic, and a pH < 7 is acidic. Remember that pH is a number that represents the concentration of hydronium ion (H+) in a solution. The equation for this is pH = -log10[H+]. If you have a pH of 9, then you can solve for the concentration of hydronium ions as follows. pH = 9 -9 = log10[H+] You can then raise both sides of the equation to the power of 10 in order to eliminate the log. 10-9=10log10[H+] 10-9=[H+] since 10log10[H+] = [H+] So a pH of 9 indicates a hydronium ion concentration of [H+] = 10-9


If a solution has a pH of 9.8 what would you consider it to be?

The solution could be described as slightly basic. Considering the pH scale, we know that neutral pH , i.e. water, is around 7. Thus, a pH of 9 means that the solution is slightly basic. More specifically, it means that there is a higher concentration of OH- ions in the solution than H+ ions.

The pH of a of solution A is 2 The pH of solution B is 4 How does the concentration of hydrogen ions compare?

Because of the logarithmic nature of the pH scale, a single step indicates a difference tenfold. As such, the difference in concentration of hydrogen ions between solutions A and B in this example are a hundred fold, with solution A having a higher concentration than solution B.

What happens when you lower a pH solution?

The concentration of H+ has increased 10-fold (10X) compared to what it was at pH 9 and the concentration of OH- has decreased to one-tenth (1/10) what it was at pH 9.


Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?

The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.

alkaline solution


What property of phenolphthalein makes it useful indicator for acid-base titrations having equivalence points in the pH range from 7-9?

The colorless solution change to a pink solution (at the pH mentioned).


A solution with higher pH levels is more?

The Ph of a base can't really increase, basicity is dependent on the P(OH) value of the base. I take it you mean "solution" in which case the answer would be: "When the pH of a solution increases, the solution becomes more basic/alkaline."


What is the pH of a solution of 0.000000001 M HCl?

[H+] = 1.0*10-9 (from the acid) + 1.0*10-7 (from water) = 1.01*10-7 ,so pH = -log(1.01*10-7) = 6.99 = 7.0Please notice that the 'calculated' pH value of 9.0 (from the 1.0*10-9 M HCl) is a very often made mistake. One should take the 'water' originating protons into account, they are majorious!
