it is almost neutral. 7.5 is the neutral acidity. above that is acidic and below that is basic.
To find the pOH, subtract the pH value from 14. In this case, for a pH of 6.2, the pOH would be 7.8.
Neutral solution: pH =7Acidic solution: pH7.
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.
that would be 1
The pOH can be calculated by subtracting the pH from 14. In this case, since the pH is 10.7, the pOH would be 3.3.
In 2016 you would be 74 years old. 2016 - 1942 = 74
74 in Roman numerals is LXXIV 74 in Roman numerals would be LXXIV
2 pH is the answer
74
the pH would be 7 - 9
acid pH < 7base pH > 7
To find the number that, when multiplied by 3, equals 74, you would divide 74 by 3. The result is approximately 24.67. Therefore, 24.67 times 3 equals 74.
To find the pOH, subtract the pH value from 14. In this case, for a pH of 6.2, the pOH would be 7.8.
pH 4 = acid pH 12= base
Calcium chloride does not affect pH so a solution of it would have a pH of 7
You need a pH paper but better is it to have an electronic pH meter.
Neutral solution: pH =7Acidic solution: pH7.
