Day 14

March 23rd

This is the end of my blog, thank you for joining me in witnessing how my experiment of 'Dissolving Tablet in Hydrochloric Acid' unraveled and how may results helped to figure out everyday situations such as a tablet that gives fastest pain relief.
Hope you all learnt something.

Day 13

March 19th

Through searching about articles related to my experiment, I found articles about gastric acids especially hydrochloric acid and information about the concentration of hydrochloric acid in the stomach.

These articles helped me through my experiment and how i performed it.  

Day 12

March 15th

Continuing on with my SRP Report I was able to finally graph my results and do my discussion and conclusion.

With my graph I decided the best option would be to do a column graph as it described what I wanted to show for my experiment in my graph.

My graph went as follows:

In my discussion we were to talk about any trends that were evident in our experiment, accuracy in our experiment, reliability of our experiment, validity of our experiment, and how we can fix problems shown in our experiment.

My discussion went as follows:

Trends that is evident in this experiment show that Panadol and Panamax dissolve around the same time making it more evident that Panadol and Panamax can both dissolve at the same rate in the stomach. Hydrochloric acid is the most dominant acid in the stomach meaning it would be ideal to use hydrochloric acid as it would be what the tablet would dissolve in, in the digestive system mainly in the stomach. This experiment is accurate as it was capable to use appropriate equipment for the experiment, e.g. measuring cylinder to get the amount of hydrochloric acid. Under the same conditions this experiment was performed this experiment 3 times to be reliable. In this experiment there only had one independent and dependent variable while the rest were controlled, this makes this experiment valid. Problems that occurred in this experiment include the fact that the Advil tablet didn’t dissolve creating problems as it was a liquid capsule. To substitute for this I decided to use aspirin instead as it was still a tablet I could have used.

In my conclusion we were to sum up our experiment.

My conclusion went as follows:

The hypothesis was incorrect as, the Advil tablet did not dissolve at all and shows that the aspirin tablet dissolves the fastest being the best medication for fast pain relief. 

Day 11

March 9th

After school I was able to conduct my experiment that I was supposed to have done the week before. I started off with setting up all my equipment and then following the method step by step in which also required me to repeat the experiment 3 times.

My results went as follows

Tablet	Time Taken to Dissolve (min)
	Test 1	Test 2	Test 3	Average
Aspirin	0:15	0:12	0:14	0:14
Panafen plus	4:41	4:58	4:35	4:45
Panadol	1:40	1:30	1:22	1:31
Panamax	1:17	1:25	1:31	1:24

Through this I was able to work through my SRP Report. My plan states that i was using Advil for my experiment but due to me getting the wrong tablet type (as i got liquid capsules) I needed to change my tablet to Aspirin and test how  fast it dissolve in hydrochloric acid. I forgot to take a photo of my aspirin tests but i have photos of the other 4 experiments.

Day 10

March 1st

I was away at school today and wasn't able to do my SRP experiment during our scheduled class lesson and on the 29th of February Ms Reid emailed me wondering what materials I would need for the experiment. I replied stating that I needed:

• 4 beakers
• 1 measuring cylinder
• 4 stopwatches
• 4 stirring spoons
• 4 heat mats
• 120mL of 0.1 M hydrochloric acid

With this equipment I would be able to conduct my experiment and see if my results will support my hypothesis

Day 9

February 23rd

Today we needed to hand up and upload our SRP Plan onto Canvas and during period 2. Once we handed up our printed plan, Mrs Reid read our plans and gave us feedback that would be helpful in writing our report.

From my plan Ms Reid asked for me to find the concentration of hydrochloric acid and how much the stomach can actually hold.

Through finding this it is found easier for me to do my experiment as I knew the exact concentration needed to conduct my experiment.

Day 8

February 20th

Today was when i was able to complete my SRP plan completely as I was able to complete my risk assessment in which needed me to sign electronically. In this I am able to know my risks for each different material used in my experiment, and find out how I can minimise if that risk can be performed in my experiment. In completing my entire plan I had a clear mindset and idea of what I wanted to do for my experiment.
