Chemical and Physical Change in Matter

waited a minute to see if there was any change to the litmus paper and then recorded my results. Test tube three was mixed with the compound and Hydrochloric acid. Most of the substances that were being tested had a physical or chemical change with the HCI. Lastly, test tube four which contained a new piece of a substance was mixed with Sodium Hydrochloric Acid. After each compound the test tubes were cleaned thoroughly and set up for the next substance that was being tested. This was repeated seven...

Thesis

Others use it as pain relievers for burns and scratches, for wart removal and splinters removal according to a website called apartmenttherapy.com3. PRODUCT Pectin for use in food is defined as a polymer containing galacturonic acid units (at least 65%). The acid groups may either be free, combined as a methyl ester, or as sodium, potassium, calcium or ammonium salts, and in some pectins amide groups may also be present. It is produced commercially as a white to light brown powder, mainly...

Chemistry Experiment

water. Wait three minutes. The reaction we concluded was NA (OH) (aq) + HCL (aq)- H (OH) + NACL. The fourth reaction was to add 10 ml of water to a 50 ml beaker. Add one drop of phenylthalein to the beaker. Record any observations. Add drops of hydrochloric acid while stirring until the mixture turns clear. Rinse any remaining material down the sink and be sure to completely wash out the small beaker. Return all materials to desk. The data we recorded was that it turned pink, with lines of purple in...

Analysis of Silver in an Alloy

in the Buchner funnel, turn the water on and wet the filter paper with the acid wash. 2. Find the Mass of the Alloy • Find the mass of the empty beaker and then place the silver alloy in the beaker and weigh that. Subtract the mass of the beaker from the mass of the beaker with the alloy in it to get the mass of the sample. 3. Dissolve the Silver • Put the alloy in a beaker, put 10-mL of 6 M nitric acid in the beaker, place a watch glass on top of the beaker and place on the hot...

Respiratory Protection Selection

has: Hydrochloric acid vapors escaping from a cylinder stored in an outdoor area. Oxygen levels are measures and found to be above 19.5 %. Referring back to the MSDS sheet for hydrochloric acid it states “it can cause severe respiratory tract, eye and skin burns. Harmful if inhaled, and may cause target organ damage “(Airgas, 2013). Because this RESPIRATORY PROTECTION SELECTION scenario is in an open/outdoor area and without much more information to go on, I assume that the hydrochloric acid...

Experiment 6- Empircical Formula of a Compound

known mass of magnesium (Mg) with hydrochloric acid, HCl (aq), to form a compound containing only the elements Mg and Cl (magnesium chloride). The mass of Cl reacting with the Mg will be found from the difference in the mass of the product and the mass of Mg used. By following the same sequence of calculations used in the Al2O3 example, you will be able to experimentally verify the empirical formula of magnesium chloride. The reaction of magnesium with hydrochloric acid is an example of a single replacement...
