Sodium Chloride

compound because both hydrogen and iodine are nonmetals. 6) Why would the bulb light up when placed in an aqueous solution of sodium chloride but not in a solid sample of sodium chloride? In a solid sample of sodium chloride, sodium and chloride are bonded together ionic and so there aren’t any free electrons to support the flow of electricity. When sodium chloride is placed in an aqueous solution, it will dissociate into Na+ and Cl- ions. These ions have mobility in the solution and are able...

Osmosis and Diffusion on Different Concentrations of Sodium Chloride on a de-Shelled Chicken

the slower rate of movement.1 2.3. The aim of this investigation is to evaluate the process of Osmosis and Diffusion on different concentrations of sodium chloride on a de-shelled chicken egg over a period of 24 hours. 2.4. My hypothesis relating to this investigation is that the de-shelled eggs in different sodium chloride solutions will absorb the water through the process of osmosis which will cause the eggs to increase both their weight and size. 2.5. The outcome...

The Effect Of Sodium Chloride Concentrations On Lettuce Seed Germination

amount of ATP the seed can generate in order to grow, the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al., 2010). The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds, Lactuca sativa. A study done by Katembe et al., (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition, therefore, preventing germination and root...

Sodium Chloride and Ml Density

as well as the density was calculated. The same process was performed to calculate the density of an unknown substance. The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1. A metal sphere weighing 15.45 g is added to 21.27 mL of water in a graduated...

Sodium Chloride

Sodium chloride, also known as salt, common salt, table salt, or halite, is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt, it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at...

Sodium Chloride and Orange Oil

the slightly toxic d-limonene. Consuming small amounts of it from substances like orange juice has been shown to produce no effect on human health. Salt, also known as table salt, or rock salt, is a mineral that is composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of ionic salts. It is essential for animal life in small quantities, but is harmful to animals and plants in excess. Salt is one of the oldest, most ubiquitous food seasonings and salting...

The Gravimetric Analysis of Chloride Salt

Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid, yet still does have some solubility. Because of these traits, the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution...

Two Types of Solids

purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour, hardness, melting point, solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours, hard, a high melting point, soluble in water and insoluble in 2-propanol; some of the physical properties of camphor...

Sodium Chloride and Water -different Concentrations

Procedure 1: Potatoes strips Six tubes of potatoes are cut at 3 cm in length and the skin is removed. They are each placed in a test tubes. Each test tube is labeled as followed: H20, 0.05 %, 0.5%,1%, and 10 %. This represents the concentration of sodium chloride of the solution in which the potatoes tubes are going to be submerged. The start time is recorded at 6 p.m. The end time is going to be after 1 hour has elapsed. The potatoes tubes are then observed for water loss or gain. Procedure 2 The...
