25 cc of an alkals solution s mixed with 8 cc of 0.75N acid solution and for complete neutralration, it further requered 15cc of 0.8N acid solution. Find the strength of the given alkali solution.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

there are infinitely many solutions.
