Expt # one particular
In this research laboratory I will try to observe in what an Alka-Seltzer tablet will melt fastest in. I need to find out if the Alka-Seltzer tablet can dissolve slowest or quickest in regular faucet water, warm water, cold water, salt water, or perhaps acidic normal water. In this lab I wall membrane develop and test a hypothesis, evaluate data and draw a conclusion. In this experiment Let me find out that in a kind of water the Alka-Seltzer is going to dissolve faster and reduced. Alka-Seltzer is one of the world's most widely known antacids. The main function is to absorb excess stomach acid.
5. Tap Water- Warm Water
* Cold Water - Salt Water
2. Acidic Water-5 cups (250 mL of water in each cup)
* A whole Alka-Seltzer tablet
My hypothesis is that the Alka-Seltzer tablet can dissolve most effective in sodium water, as well as the slowest in cold normal water. I think it will dissolve quickest in sodium water because of the salt. I do think it will melt slowest in cold normal water because the cool water does not help the Alka-Seltzer dissolve quicker.
Type of Water| Dissolve Period
Tap Water| 25. twenty seven seconds
Acidic Water| 25. 17 secs
Warm Water| 25. thirty seven seconds
Cool Water| 28. 21 seconds
Salt Normal water (2 teaspoon of salt)| 38. 41 seconds
Q. Are you going to a whole or perhaps half a tablet of Alka-Seltzer tablet?
A. I will use a whole Alka-Seltzer tablet with this lab test. Q. How will you measure how fast it dissolves?
A. Let me use a timer to time how fast the tablet dissolves. Queen. How much normal water will you employ?
A. Let me use two hundred fifity mL of water.
Queen. What safety precautions should you have?
A. Avoid taste any of the water and don't drink water used for the experiment.
I actually therefore deduce my speculation was wrong. The tablet dissolved quicker in acidic water because of the vinegar and slowest in the salt water because of the salt. In...
