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.
When mixing a solution at pH 4 with a solution at pH 8, the final pH will be between 4 and 8. The resulting pH will depend on the ratios of the two solutions being mixed. If equal volumes are mixed, then the final pH will likely be around 6.
