Tomato Juice is roughly a pH of 4
An acidic solution. Solutions with a pH below 7 are considered acidic.
The pH of the second solution must be neutral (pH 7), as mixing an acidic solution (pH 4) with a basic solution (pH 7) would result in a pH closer to 7. This indicates that the pH of the unknown solution is around 7 to yield a final pH of 5 when mixed with the pH 4 solution.
The difference in hydrogen ion concentration between solutions with pH 4 and pH 5 is tenfold. A solution with pH 4 has 10 times more hydrogen ions (H+) compared to a solution with pH 5. This is because the pH scale is logarithmic, with each unit change representing a 10-fold change in hydrogen ion concentration.
Standardize the pH meter using a buffer solution of known pH value.Basically take buffer of pH value 4.Then set zero reading in the pH meter.Now remove unknown buffer solution.(take care with atmospheric temperature.)
A solution with a pH of 4 is considered acidic. It has a higher concentration of hydrogen ions (H+) compared to a neutral solution with a pH of 7. Solutions with pH values below 7 are progressively more acidic, while those above 7 are progressively more basic.
pH 4 = acid pH 12= base

A Ka value of 1.25 x 10-4 indicates a weak acid. This means that the indicator would be most effective at detecting solutions with a pH close to the pKa value of the indicator, which is approximately 3.9. Therefore, the indicator could be used to determine if a solution has a pH above or below 3.9.
A solution with a pH of 4 is considered acidic. It has a higher concentration of hydrogen ions (H+) compared to a neutral solution with a pH of 7. Solutions with pH values below 7 are progressively more acidic, while those above 7 are progressively more basic.
Phenolphthalein (3,3-bis(4-hydroxyphenyl)isobenzofuran-1(3H)-one) is a pH indicator or an indicator in volumetry; the color is pink in basic solutions and is colorless in acidic solutions.
Any solution with a pH below 7 is considered acidic at 25°C. This means that solutions with a higher concentration of H+ ions (lower pH values) will be acidic. Additionally, a solution with a pH around 7 will be neutral, while solutions with a pH above 7 are considered basic.
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.
