This is a lab called Enthalpy and Entropy of Borax Dissolution and I just can't seem to get the right answers... Please help me fill in the blanks

The _____ (acid/HCl?)is placed in the buret and the ____ (base/borax?) is placed in the flask beneath
the buret.

For this experiment bromocresol green is a(n) indicator and added to the _____ (borax/basic?) solution before titration.
The color of bromocresol green indicator is yellow when pH < 4, green when pH 4- 5.3 and blue in pH > 5.3.

The titrant volume when the bromocresol green changes color is called the _____.

    I know I'm to help fill in the blanks but I'm a little confused. The last blank should be "end point." I think HCl is the first one, borax the second. Is this what you need?

    Sorry, if I wasn't very clear. I've tried both acid and HCl for the 1st blank and borax and base for the 2nd blank, but still wrong. end point is right though!

    Try it the other way around. You may have the acid in the beaker and the borax in the buret.l
