Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup
