30.00 mL of a H{eq}_2{/eq}SO{eq}_4{/eq} solution with an unknown concentration was titrated to a phenolphthalein endpoint with 47.69 mL of a 0.1259 M NaOH solution.

What is the concentration of the H{eq}_2{/eq}SO{eq}_4{/eq} solution?

_____ M

Strong Acid - Strong Base Titration:

Titration is the process of determining the concentration of an analyte through the addition of a standard titrant with known concentration. An Indicator, such as phenolphthalein, is added to the solution to observe the color change in the solution signaling the end point or the completion of the reaction.
