Respuesta :
The upward curve of the water shows adhesion while the dome shape represents cohesion, the the addition of the salt shows the evidence of solute, this experiments shows the covalent bonds nature and pH of the sample is neutral and the sample is water.
The margins of the liquid bent upward when Amanda poured some of the liquid into a test tube, demonstrating adhesion. Another test container was completely filled by Pol, and the liquid formed a modest dome as proof of cohesion.
Amanda noticed that the Solute had been dissolved by the liquid after adding table salt to the first test tube and shaking it. These observations collectively demonstrated the existence of covalent bonds.
Since the sample's pH was found to be 7, Pol concluded that it was neutral. The unidentified liquid is Water, according to all the information Amanda and Pol acquired.
