PH is the negative logarithm of hydrogen ion concentration
Assuming the concentration of hydrogen ion is 0.1, then - log0.1 = 1, then the pH of the solution is 1
In fact, it's a good calculation method
Definition of logarithmic function
Why is the range of y = logax all real numbers
The inverse function of y = logax is y = a ^ x, and the domain of y = a ^ x is r, so when y = the range of logax, R
Under the function y = root, the definition field with 2 as the base (4x-3) as the logarithm is?
The definition field of 1 ≤ 4x-3 is [1, positive infinity]
