Question

amanda and pol were in science lab, trying to identify a color - less liquid. their observations were as follows: acid adhesion base cohesion covalent hydrogen ionic neutral solute solvent vinegar water when amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an exam when pol filled another test tube to the top, the liquid formed a low dome, which is evidence of when amanda added table - salt to the first test tube and shook it, she noted that the liquid had dissolved the all of these observations i pol determined that the ph of the sample is 7, which shows the sample is based on all of the evidence, the unknown liquid is

Explanation:

1. When the edges of the liquid in the test - tube curve upward, it is adhesion (the attraction between the liquid and the test - tube surface).
2. When the liquid forms a low dome at the top of the test - tube, it is cohesion (the attraction between liquid molecules).
3. When the liquid dissolves table - salt, it is a solvent.
4. A pH of 7 indicates the sample is neutral. Based on all these properties, the unknown liquid is water.

Answer:

1. adhesion
2. cohesion
3. solvent
4. water
5. neutral
6. water
