Answer:
Solving this equation gives a result of approximately -79%
Step-by-step explanation:
It appears that you are trying to calculate the percentage change in pH between two values, pH 1.46 and pH 7.00. To do this, you can use the formula:
Percentage change in pH = 100% x (pH 1.46 - pH 7.00) / (pH 7.00)
Plugging in the values, the formula becomes:
Percentage change in pH = 100% x (-5.54) / 7.00
Solving this equation gives a result of approximately -79%. This means that there was a 79% decrease in pH from pH 1.46 to pH 7.00.
It is important to note that this formula is used to calculate the percentage change in pH between two values. If you are trying to prevent a change in pH, the formula would not be applicable.
