If you add acid to pure water, you lower the pH below 7. There isn't any way to add acid to water to raise the pH.

Why is the PH scale 1-14?
hydrochloric acid (in stomach) lies in pH1 and so does sulfuric acid (in car batteries), the most acid rain ever recorded lies in pH3 and so does vinegar (ethanoic acid). orange juice in pH 5 and clean rain in pH6. distilled water is neutral so it's pH7. Toothpaste is pH9 smelling salts (ammonia) pH11, washing soda, pH12 and caustic soda pH14.
How many times more acidic is a solution of pH 9 than a solution of pH 5?
Each number on the pH scale represents a 10-fold difference from the number before or after it, so that pH5 is 10x more acidic than pH6 which is 10x more acidic than pH7. Since the difference between 9 and 5 is 4, the acidity would be 4 tens multiplied together: 10 x 10 x 10 x 10 (or 104), BUT.... the question asks for the difference in acidity at pH9 compared to pH5. pH9 is weaker, so we use the inverse. pH9 is only 1/104 as acidic as pH5.
What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice?
Question: What is the effect of the acidity of potato juice on the volume of foam produced when hydrogen peroxide is added to potato juice? In this investigation, the prediction that if the acidity of potato juice is decreased then the volume of foam was increased was proven incorrect. Catalase is damaged by acid. The lowest foam volume was 24 ml with the highest acidity, pH6, However the highest foam volume was an average of 42 ml with the second lowest acidity level,pH8 The third highest volume was 35 ml with the second highest acidity level pH7, and the second lowest foam volume was 30 ml with the lowest acidity level pH9.
How much more basic is a solution with a pH of 11 than one with a pH of 9?
for every value of 1 integer in either direction, there is a difference of 1 magnitude of acidity or basicity. since pH 11 and 9 are considered bases, the weakest base is pH9. 11-9 = 2, therefore there is an order of 2 magnitudes greater basicity with a pH of 11 over pH 9, one hunder times as basic
An acidic solution having a pH of 4 is how many times more acidic than a solution of pH9?
The pH scale represents a count of ions (hydrogen), or more accurately the "activity" of hydrogen ions. The pH is the negative of the logarithm (base 10) of the concentration in moles per liter. A solution with a pH of 4 is 100 times as concentrated as one with a pH of 6.
Are ph9 strong base?
It is weak
Your blower motor blowes when you turn your motor off on your 2002 Chevy 1500 truck What is the problem?
There seems to be a problem with your 2002 Chevy 1500 truck. I think you may need to check out the left water tank as the acidity may be PH9. Hope this helps

Is methyl red pink at pH9?
it is red in pH under 4.4, yellow in pH over 6.2, and orange in between. Basically color of methyl red at pH 6 is ORANGE.
What is 1 Armstrong unit equal to nano meter?
Assuming the question refers to an Angstrom unit, it is a tenth of a nanometre. By contrast, one Armstrong unit is a measurement of phosphatase and equals 1 mg of phenol liberated in 30 minutes at 100 degrees Fahrenheit and pH9. It is highly unlikely that someone can find a relationship between this and a nanometre.
