The question is incomplete, the complete question is:
Standardization of a Borax solution (Na2B4O7). A student titrates a 20.00 mL sample of an aqueous borax solution with 1.044 M H2SO4. It takes 2.63 mL of acid to reach the equivalence point. Knowing it takes 1 H2SO4 to neutralize 2 Na2B4O7, what was the concentration of this Borax solution?
<u>Answer: </u>The concentration of borax solution is 0.069 M.
<u>Explanation:</u>
To calculate the concentration of borax solution, the formula used is:
....(1)
where,
are the n-factor, concentration and volume of sulfuric acid
are the n-factor, concentration and volume of borax solution.
We are given:
Putting values in equation 1, we get:
Hence, the concentration of borax solution is 0.069 M.
