Home Chemistry 16
Updated 6/8/2023
Now that I have a new batch of Red Cabbage indicator. I would like to investigate some of the chemistry of a recently collected sample of seawater, specifically the following:-
- The pH of seawater.
- If adding eggshells changes the pH.
Background to this
Eggshell, contains Calcium Carbonate $\ce{CaCO3}$ when added to vinegar $\ce{CH3COOH}$ the pH value increases.
Related information
Adding eggshell to vinegar increases the pH of the vinegar. I will write up my experiment / results and share this. What I want to know is can eggshell do the same to seawater.
This may be a possible solution to ocean acidification.

Write-up
You can find my write up for this experiment in PDF here. You may want to right click and download, otherwise it will probably just open in a browser. Provided as-is, but it should cover what I did, my results and conclusion.

The red cabbage indicator that I am using works fine. However it looks rather red, further investigation and starting discussion on Science Forums about this, suggested a cause and solution.
In essence the indicator is acidic, hence the read colour rather than the purple neutral colour.
I have now made up a new batch, which looks a lot better
The image above illustrates the old indicator on the right hand side, the new is in the beaker on the left. You can see quite a big difference in colour.
I have extracted the pH colour scale from the original infographic below
Video
There is a 3 min Video here that I made while making the new batch of indicator up.
- Add hot water to beaker
- Add red cabbage to water
- Mix (until water is the required purple colour)
- All to cool
- Add to regent bottle
Created more indicator as required.

Code Club – Summer 2023 code along
Just been sent this by code club
Get set for a summer codealong! Join the Code Club team on Tuesday, 23 May, 10:00–11:00am BST/GMT+1.
This is a great opportunity for young people aged 9 and above to come together and code one of our simple and fun projects! No previous coding experience is required to participate in this codealong. You can include as many classes or groups of learners as you would like, as long as they can all follow along comfortably on the day.
Learners will create a summer day in the garden animation, using the simple coding language, Scratch. Learners will have the opportunity to add their creativity and personality to their projects, and a digital certificate will be made available to everyone who participates.

Front End Development
As previously mentioned, Free code camp send out lots of really useful material. As there seems to be interest at code club with regard to making games. The following from recent mail-outs may be of interest.
1. freeCodeCamp just published a new Front End Development course. You can code along at home and build your own game in raw HTML, CSS, and JavaScript. Then you'll learn how to refactor your game to make use of the Model-View-Controller design pattern. You'll then add TypeScript to improve the reliability of your code, and React to make your game more dynamic. This is an excellent project-oriented course for beginners.

Code Club 6/5/2023
The next Paignton Library code club is on Saturday 6th May 2023 10 am to 12:00. We can carry on with what we are doing,
Useful Links
Beginner Level
Roblox
As Roblox is very popular and allows you to develop within the game the following may be useful.
Note you need your own laptop with this installed so you can develop Lua projects for Robox. You can use Replit to learn Lua but need an account.
GNU / Linux BASH
This is something that once mastered can be very beneficial
Python
Web Site Creation
Other
Free Code Camp offer a wide range of follow along interactive courses, tutorials etc. You will need an account but it is probably worth getting on.
- Vfsync – this is a Linux terminal in a browser.
