Build a titration curve for the following scenarios. Make sure to label your accesses and anyother appropriate pieces of data. Each curve should have a minimum of 4 data points, but youcan use the following to help structure your curvea) Initial pHb) pH at Veqc) pH=pka (if applicable)d) pH when excess titrant is addede) Additional pH point near Veq for Strong Acid/Strong Base titrations (in order to see thesteepness of the slope) OR additional pH point in buffer zone for titrations with a Weakcompound.
