1 mL de la solución de tiosulfato de sodio 0,1M, valora aproximadamente 27, 03 mg de Cl3Fe, 6H2O, luego para 10 mL de la solución primaria amarilla, aproximadamente el final de la valoración estará cerca de los 17 mL de tiosulfato gastados.
Can someone tell me the meaning of valora in this context? Would it be 'equal to'?

: I prefer "titrates", since it's talking about a titration. "Measures" could apply, but I think the best choice is "titrates", it's the most accurate in my opinion.

Comment: "Thank you so much. That is what I ended up guessing, but wasn't sure it could be used as an intransitive verb as here."

I had a change of heart and mind...
I think they are talking about equivalencey in term of titrating thioslufate with Fe3+.

In this case, the Fe3+ will oxidize the thiosulfate into sulfate I believe... S2O3^2- ------> SO4^2-

unwizard:
3.2. Homogeneous catalysis
Thiosulfate ion [S2O3]2- is oxidised to tetrathionate ion [S4O6]2- by Fe3+:
2Fe3+ + 2[S2O3]2- <----> 2Fe2+ + [S4O6]2-
Fill two test tubes with 4 ml 0.1 M Fe(NO3)3 solution and add to one of them 1 drop of 0.1 M Cu2+ solution. Finally, add 5 ml of 0.1 M Na2S2O3 solution to both test tubes and compare the time required for the deep color of the solutions to disappear.
(Note: Fe3+ forms with thiosulfate ions a deep brown colored complex!)

In this particular case, the thiosulfate is oxidized to tetrathionate.
It's also possible to oxidize it to sulfate...

Fe+3 + S2O3-- = Fe+2 + S4O6-- 2Fe+3 + 2S2O3-- = 2Fe+2 + S4O6--
Fe3+ + S2O3-- = Fe2+ + S4O6--
Apparently, the product of oxidation is tetrathionate...
Here, the meaning of "equivalency" is that 0.1 ml of 0.1 M thiosulfate solution is titrated (completely reacts) with 27.03 mg of FeCl3.6H2O solution.
