4 if its a base
1 if its an acid
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 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.
A pH of 4 would denote a solution that is acidic. pH values below 7 indicate acidity, with lower values representing stronger acidity.
The difference in strength between pH 9 and pH 4 is significant. As pH is measured on a logarithmic scale, each whole number change represents a 10-fold difference in acidity or basicity. In this case, pH 9 is 100,000 times stronger in basicity compared to 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 pH scale is from 1-14 Strong acids are 1-4
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.
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
A car battery has a stronger pH compared to lemon juice. Lemon juice typically has a pH around 2, which is acidic, while a car battery has a very low pH due to the strong sulfuric acid electrolyte it contains.
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.
The final pH would be less than 5 because the stronger acid (pH 4.0) would have a greater effect on the overall pH than the weaker acid (pH 6.0). To calculate the exact final pH, you would need to know the exact concentrations of the two solutions and perform a Henderson-Hasselbalch calculation.
