pH 9 - pH 4 = pH 5
It is stronger by 5 pH.
No, a lower pH value indicates a stronger acid. Therefore, pH 3 is stronger than pH 4.
The pH scale goes from 0 to 14. 7 is neutral, and the further numbers get from 7, the stronger the substance gets. Thus pH 2 is stronger than pH 4.
A decrease of 2 pH units corresponds to a 100-fold increase in hydrogen ion concentration. Therefore, a pH of 2 is 100 times stronger in terms of acidity compared to a pH of 4.
The strength of an acid or base is measured on a logarithmic scale, meaning a change of 1 pH unit represents a tenfold difference in acidity or basicity. Therefore, a substance with a pH of 9 is 1,000 times stronger in basicity than a substance with a pH of 4.
A pH of 1 is stronger (more acidic) than a pH of 4. Each whole number change in pH represents a tenfold change in the acidity or alkalinity of a solution. Therefore, a solution with a pH of 1 is ten times more acidic (has a higher hydrogen ion concentration) than a solution with a pH of 2, and 100 times more acidic than a solution with a pH of 4.

That depends on what you are referring to, a stronger base or acid. The pH scale logarimithically scales back the concentration of H3O+ in solution such that lower values conincide with greater degrees of acidity (specifically a magniture of 10 for each whole value). The stronger acid of the two values is most certainly 1.5, however the stronger base is 4
Ph 4 is not necesarilly stronger than pH 6. It depends on your vantage point. There are 14 levels of pH. 0, 1, 2 ,3 etc. The level 8 is a neutral substance. The closer to 0 u go, the stronger the BASE. The closer to 14 you go, the stronger the ACID. Therefore, it makes sense to say that 4 is a stronger base than 6 because 4 is closer to 0, however, 6 is a stronger acid than 4 because it is closer to 14. It is important to know however that botch 4 and 6 are bases, and not acids, because they are both below 8. Though this is true, it is possible for one to be more or less acidic than the other, and this is true with both acids as well when referring to bases.
316pH is defined as the negative log of the hydrogen ion concentration. A pH of 2 is 10 times stronger than a pH of 3. A pH of 2 is 100 times stronger than a pH of 4.The easiest way of comparing pH of 3 and 5.5 might be to convert the numbers back to hydrogen ion concentrations, [H+].pH 3 means [H+] = 10-3 which is equal to 0.001 MpH 5.5 means [H+] = 0.00000316 MThis means that pH 3 is 316 times stronger than pH 5.5
100
4 if its a base 1 if its an acid
A pH of 3 is more acidic than a pH of 4 and a pH of 4 is more alkaline than a pH of 3. The pH balance of a swimming pool is about 7.6 meaning it is neither acidic or alkalinic, it is neutral!
In pH 3, the concentration of hydrogen ions is 10 times higher than in pH 4. Therefore, there are 10 times more hydrogen ions in pH 3 than in pH 4.
