The Formation of Silver Crystals in a Microgravity

The Formation of Silver Crystals in a Microgravity Macomb Mathematics Science Technology Center – Warren Consolidated Schools Environment By Sydney Waynick, Steven Prascius, and Hunter Montrose

Macomb Mathematics Science Technology Center is Spearheading Warren Consolidated School's Participation in SSEP

Properties of Silver Crystals �Metal Organic Framework �Store natural gases �Cubic nature Cubes Octahedrons Dodecahedrons Tetra hexahedron

Cubic Varieties

Applications �Gas storage Vehicles Space flight �Humans are able to go further than ever before! �Carbon capture �Separating and purifying gases

Crystal Storage Gas molecules can be stored at a higher density on the surfaces of MOFs than in conventional tanks �Three-dimensional metal-organic framework with pore sizes in the nanometer range �Greater porosity = greater surface area �Rapid Development

Silver Crystal Formation Chemical reaction between Ag and Cu Cu(s) + 2 Ag+(aq) → Cu 2+(aq) + 2 Ag(s) Coiled Copper wire Greatest surface area http: //2012 books. lardbucket. org/books/general-chemistryprinciples-patterns-and-applications-v 1. 0/section_08_08. html

Experiment �Purpose To determine the effect of microgravity on the formation of Silver Crystals �Hypothesis We predict that the silver crystals will form the same as they do an earth in an environment with microgravity because the reaction does not depend on gravity. Neutral buoyancy of water is similar to microgravity

Materials Silver Nitrate 5 m. L water 20 cm copper wire

Procedures (Pre-Launch) 1) Prepare a 0. 1 molar solution of Silver Nitrate 2) Pour the Silver Nitrate solution into the FME tube 3) Place clamp above the Sliver Nitrate solution on the tube 4) Place the 20 cm long coiled copper wire above the clamp and seal the tube Silver nitrate solution

Data collection �Comparison: Ground vs. Space sample �Size �Shape �Color

Ground Based Results Twining Shape Size

Ground Based Results Color Tarnished / Untarnished
