Sodium hypochlorite

the Iron was attracted to the Magnet. When it comes to the separation of Sand and Sodium chloride, they were separated because of the unique property of Sodium Chloride which is solubility. When the mixture of Sand and Sodium chloride was mixed in the water, the sodium chloride had the capacity of being dissolved in the water leaving the sand undissolved. When the mixture was filtered using a filer paper, the Sodium chloride went through the filter paper because it was soluble in water but the…

concentration of a sodium hydroxide solution can be determined by titration potassium hydrogen phthalate (KHP) with an unknown concentration of sodium hydroxide NaOH. The average molarity of NaOH determine by the moles and volume of the KHP and NaOH. (Eq 1). KHC8H4O4(aq) + NaOH(aq) = H2O(l) + NaKC8H4O4(aq) (Eq 1) The unknown concentration of white vinegar can be determined by the white vinegar with the known concentration of sodium hydroxide…

1. Existing knowledge, research and views: The separation of the sulfur and iron powder was accomplished through magnetism. When combining the sulfur and iron powder to form a mixture, a magnet can be used to attract the iron separating it from the sulfur. Unlike the iron and powder, the salt and sand were separated through filtration. This is a method which separates solids from liquids. In the experiment, the mixture of salt, sand and water are separated as it is poured through a funnel with…

Upgrading their home's kitchen countertops is at the top of the dream to-do list for many homeowners. Not only does it considerably add to the value of a home, it also makes cooking and having guests over much more enjoyable. While many homeowners opt for granite or marble countertops, few materials have as many benefits as a lovely soapstone. Bella Stone Cincinnati offers some tips on how to maintain this gorgeous stone and add to its beauty for years to come. Soapstone countertops are…

Exp D. Post Lab Questions 1. What is the purpose of the concentrated sulfuric acid in the first step? The purpose of using concentrated sulfuric acid is to activate the reaction of salicylic acid and acetic anhydride and produce the acetylsalicylic acid, which is aspirin. The sulfuric acid is used to protonate oxygen atom of a carbonyl group of salicylic acid. 2. What would happen if the sulfuric acid were left out? Removal of catalytic acid from the reaction would slow down or not proceed…

molarity of the unknown substance. I believe that it will take around three hundred drops of sodium hydroxide (NaOH) for it to be able to reach to its endpoint of the unknown substance. My reason behind my hypothesis is… Methods In this lab experiment we use a buret to measure the amount of pure water we decide that we need. A weight boat to be able to measure the sodium hydroxide(NaOH) on the triple beam balance. We also used a beaker to put our…

REFLECTIONS FOR LAB 4- FRICTION Lab 4.1 to 4.3 is about all the different frictions. We did 3 different labs. 4.1 was pulling a block across different surfaces and finding the difference in friction. 4.2 was about pulling multiple blocks across different surfaces and finding the difference in friction. 4.3 was about pulling blocks but in a bigger surfaces area. In Lab 4.1 we had to pull different blocks across different surfaces. The surfaces were a tabletop, wax paper, paper towel, fine…

give information on how the compound would react and behave in the local landfill and surrounding environment. The similarity of the qualitative results of the unknown compound and the known compound further suggested that the unknown compound was sodium sulfate. During the third week of lab, the group conducted the quantitative solubility test to determine the saturation point of the compound in water. If a precipitant formed, vacuum filtration would be used to figure out the amount of solid…

Concentration of a Weak Acid Solution • Obtain an unknown acid solution (90 mL) and three 250 mL beakers. Make sure the beakers are clean. • Acquire 0.1 M of NaOH solution for this experiment and make sure to determine the specific molar concentration of sodium hydroxide utilized. • Obtain a buret and make sure to rinse it with tap water, deionized…
