Bleach Hypothesis

Question

Once the pH level of various water sources, namely: swimming pool water, tap water, mineral water, river water and sea water has been established, will the pH level increase at the same rate for each water source when adding the exact amount of bleach to each and decrease at the same rate when adding the exact amount of vinegar to each?

Hypothesis

I believe that the pH balance will not increase or decrease at the same rate due to the various chemical components already in each water source of which, bleach and vinegar will have their own unique reaction due to their chemical composition.

Aim

To prove that the tested pH balance of the various water sources will be affected differently when adding the exact same quantity of bleach and vinegar to them.Introduction

My research on the internet has established that the pH scale ranges from 1 to 14, with 7 being considered neutral. pH refers to the hydrogen

However, each water source has its own unique chemical composition. My project, therefore aims to prove that the pH balance of each water source will change at different rates because of their own chemical composition after bleach and vinegar have been added in equal quantities to each source.

Trends/patterns:

There were the following patterns:

The pH level stayed consistent when the test was repeated.

Bleach raised the pH level of all water sources.

Vinegar decreased the pH level of all water sources.

Irregularities:

There were no irregularities in my results
