Determining how the temperature affects the pH of milk using titration

Hi, im writing a work for my internal assessment for Chemistry on Determining how the temperature affects the pH of milk using titration. I will conduct the experiment with titration with NaOH (I will and phenolphthalein). I have trouble finding sources I can use, so maybe someone has written similar work or knows were I can find good sources and can help me or just some tips :smile:

Hello Mirta728!

I'm happy to help you with your enquiry!

I suggest using scientific articles, online resources, books and laboratory manuals to gather information.

You can find scientific articles in academic databases such as
- ScienceDirect,
- PubMed
- Google Scholar.
Online resources can be found on websites such as
- ResearchGate
- Academia.edu.

You can access books on dairy chemistry, food science or analytical chemistry by borrowing them from your school or university library or by searching for digital copies online.

Tips and tricks

Laboratory manuals or protocols from reputable institutions or organisations may also provide relevant information. To ensure accurate results, use good quality reagents and equipment, use a standardised method for measuring pH, take several readings at each temperature, consider using a control group, and keep accurate records.
