You are asked to purchase one head of red cabbage for this assignment, ahead of time.
Devices needed include a food processor, smoothy maker or juice maker, whatever brand, and a few clear glasses.

A number of household aqueous solution of your choice (food, drink, cleansers etc.).
Guidelines
This assignment involves two parts, making red cabbage extraction as pH indicator, and determining the pH values of a few household items.

The youtube video gives you a clue how to make the extract. You don’t have to follow it step by step, as long as you make an extract that works, safety. In case you plan not to complete the entire assignment the same day, your red cabbage extract need to be stored in refrigerator to prevent it from going bad ( https://www.youtube.com/watch?v=a6dYHEC8A9g )

Working on household items, it is easier to work with items that has no color or light colored, otherwise the pH related color will be covered by the original dark color, becoming unidentifiable. For those items the liquid is sticky or cloudy, it will work better if filtered first, obtaining transparent, non-sticky liquid.

The household items should cover from acidic to basic, it is your choice of how many items to work on. It is highly recommended that you take images of your item before and after adding to the extract to easily compare color change.

Safety
This process involves using of sharp tools, making your safety analysis with the entire process in mind, and apply safety measures accordingly.
Report/reaction equations
This is a benchtop work assignment, please write your lab report in full report format. Report all your items with your result, your analysis of why (reasons) and as much as you know about the item and function, etc.
