Question
Background
Hypothesis
How much water will the sodium polyacylate hold? How much salt will it take to dissolve it all?
Sodium polyacylate turns from a powder to a gel-like substance when mixed with water and dissolves when mixed with salt water.
The powder will soak up 100mL of water and 50mL of salt water will dissolve all of it.
Our experiment led to our two original questions being answered, and our hypothesis being wrong. The answer to our first question was 187mL, and the answer to our second question was 20 grams of salt mixed in 150mL of water. Our hypothesis was wrong because we underestimated how much water it would absorb, and how much salt it would take to completely dissolve the sodium polyacylate.
Abstract
High school Chemistry students used a diaper to get sodium polyacylate and they had to come up with a lab. The students came up with testing to see how much water the sodium polyacylate would hold and how much salt it would take to dissolve it.

We took the 2.1g of sodium polyacylate and added 40 mL at a time to it until it couldn’t hold anymore. Next we mixed 20g of salt into 150mL of water and poured it over the sodium polyacylate until it was completely dissolved. 2. 1.
