which procedure would best allow a scientist to observe a chemical property of hydrochloric acid (hcl) solution?\no cooling the hcl solution until it becomes solid, and measuring this temperature\no adding zinc to the hcl solution and observing whether or not bubbles are produced\no placing a conductivity probe into a beaker of hcl solution to determine if it conducts electricity\no measuring the mass of and volume of a sample of hcl solution to find its density

Answer

Brief Explanations:

A chemical property is observed when a substance undergoes a chemical change. Adding zinc to HCl solution causes a chemical reaction (Zn + 2HCl → ZnCl₂ + H₂), producing hydrogen gas which appears as bubbles. Cooling to solid is a physical change related to melting - point, conductivity is a physical property, and density is a physical property measured without a chemical change.

Answer:

adding zinc to the HCl solution and observing whether or not bubbles are produced
