Halite (/ ˈ h æ l aɪ t, ˈ h eɪ l aɪ t /), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl).Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on inclusion of other materials, impurities, and structural or isotopic ...The crystal structures of galena (PbS) and halite (salt or NaCl) are identical, so it is not surprising that the two exhibit similar perfect cubic cleavage. ... Usually, galena's distinctive lead gray color, high specific gravity and cubic cleavage are enough to identify it, but at first glance there are a couple of minerals that might be ...To calculate the specific gravity of mercury, you need to follow a couple of steps: Take a volume of mercury, say V = 10 mL. Measure the mass of the volume: m = 135.34 g. Measure the density of mercury: ρ = m [g]/V [cm³] = 135.34 g/ 10 cm³ = 13.534 g/cm³. Take the density of water: ρw = 0.997 g\cm³.The specific gravity of a substance compares its density to that of water. Substances that are more dense have higher specific gravity. ... Halite breaks between layers of sodium and chlorine to form cubes with smooth surfaces (figure 6). A mineral that naturally breaks into perfectly flat surfaces is exhibiting cleavage. Not all minerals have ...The specific gravity of a substance compares its density to that of water. Substances that are more dense have higher specific gravity. HARDNESS. ... Halite breaks between layers of sodium and chlorine to form cubes with smooth surfaces (figure 6). Figure 6.

Most notably, CZ's specific gravity far exceeds that of most gemstones. Photo by humanfeather. Licensed under CC By 3.0. Table of Specific Gravity Values The most common equation for the specific gravity (SG) of a mineral is this: It's pretty simple to work out: 1. Weigh the mineral in air (literally put in on the scales like normal) 2. Suspend the mineral in water for the second weighing. Legend has it that is was Archimedes who discovered that the weight of the mineral in air minus its weight ... Halite is easy to identify because it tastes salty and dissolves easily in water. Broken fragments of halite may be nearly cube-shaped. In Kansas, salt is found in thick beds deep underground. Salt in these thick layers is known as rock salt.
