No entirely sure what you are asking.

pH indicates the acidity of the solution being measured. it is the negative log of the free H+ ion concentration. so pH = - log[H+]. A pH below 7 indicates acidity a pH above 7 basic solutions (in the presence of water).

How do you get the inverse of a number?

To find the inverse of a number, you take its reciprocal. For a non-zero number ( x ), the inverse is ( \frac{1}{x} ). If you are looking for the additive inverse, it is simply the negative of the number, which is ( -x ).

What does an inverse operation look like?

You just simply flip the fraction or number. Example: The inverse of 2 is 1/2 and vice versa


What is the inverse of y equals x?

The inverse of the function y = x is denoted as y = x. The inverse function essentially swaps the roles of x and y, so the inverse of y = x is x = y. In other words, the inverse function of y = x is the function x = y.


Another name for additive inverse?

As far as positive numbers are concerned, the additive inverse of a positive number is a negative number with the same magnitude (i.e. the additive inverse of 5 is -5). It would be wrong to simply say that "negative" and "additive inverse" are correct, because the additive inverse of a negative number is a positive number.


How do you find the multiplicative inverse for fractions?

To find the multiplicative inverse of a fraction, you simply flip the fraction. This means you swap the numerator and the denominator. For example, the multiplicative inverse of ( \frac{a}{b} ) is ( \frac{b}{a} ), provided that ( a ) and ( b ) are not zero. When you multiply a fraction by its multiplicative inverse, the result is 1.


WHAT integer has its own additive inverse?

Every integer has its own additive inverse, which is simply the integer multiplied by -1. For example, the additive inverse of 5 is -5, and the additive inverse of -3 is 3. Therefore, all integers, including zero, have their own additive inverses. In summary, any integer ( x ) has an additive inverse of ( -x ).


What is the inverse for the equation 7x plus 3?

To find the inverse of a function, simply switch the variables x and y. So for the function y=7x+3, the inverse would be x=7y+3, or y=(x-3)/7.

What is inverse of a function?

Simply stated, the inverse of a function is a function where the variables are reversed. If you have a function f(x) = y, the inverse is denoted as f-1(y) = x. Examples: y=x+3 Inverse is x=y+3, or y=x-3 y=2x+5 Inverse is x=2y+5, or y=(x-5)/2


Is hydrogen a compound or a mixture?

Hydrogen can be an atom (H1), a molecule (H2 or normal hydrogen), an isotope such as deuterium or tritium. Ionized Hydrogen is simply a proton.
