    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 314

    Making Sodium Chloride Equipment: Method: 1. Firstly‚ safety measures were taken by putting on laboratory coats‚ wearing safety goggles and tying long hair back. This was to protect clothing‚ eyes and to avoid burning as the experiment included dealing with open flames. 2. The equipment needed (as shown and labelled in picture A) was collected. 3. Using a measuring cylinder for each‚ to be exact with measurements‚ we measured out 10cm³ of HCl and 10cm³

    In the experiment‚ we tested a sodium chloride solution. Along with the tested solution‚ control groups (water and sodium phosphate) were used to be help understand whether or not NaCl was a buffer. Water was the negative control group and sodium phosphate was the positive control group. If NaCl was a buffer than the pH would be stabled as the sodium phosphate buffer. If NaCl was not a buffer than the pH would fluctuate like the negative control‚ water. During the first trial and prior to the drops

    From the experiment‚ it was determined that Sodium chloride had a crystalline structure‚ even after being broken into smaller pieces with a hammer. Even though there was two different types of Sodium chloride‚ coarse and fine‚ they still had a symmetrical‚ three-dimensional shape. All ionic compounds have this structure. It was also found that Sodium chloride had a high melting point and sugar had a low melting point. This is because Sodium chloride is ionic and the bonds holding it together take
