When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.
