When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

From the above‚ here is what came out of the production meeting. • Although EPA 624 does not require an MSD‚ I recommend you continue to run one when you have an extra (fourth) vial. This should meet any Waste Management contract requirement of spiking each sample during the year (I’m assuming the WM contract includes 624 samples – the main intent is to spike all groundwater samples during the year). Also‚ you could run a duplicate‚ which requires only one more vial‚ when you have a sample (possibly

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

“Morton Salt“ “No one knows Salt like we do”. Morton Salt generates a never-ending supply of new products in covering all possibilities where salt can be used and is not focusing on only one type of salt e.g. Culinary Salt. During over 160 year’s history‚ Morton Salt never stopped developing new salt products and finding new niche markets. Salt is not seen as a mundane product that is only used to salt e.g. food but even more as science. Morton Salt is presenting on his website how various salt

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is

INVESTIGATE FACTORS INFLUENCING THE SOLUBILITY OF SALTS Research question How does temperature affect the dissolving time of various salts.? Hypothesis I predict that with water of high temperature the salts will dissolve quicker. Controlled Variable Amount of water (solvent) Amount of salt used (solute) Type of cups taken and their sizes Independent variable Temperature of water Dependent variable Time taken for each salt to dissolve Material Required Measuring

A student was assigned a certain task by his teacher in chemistry lab. During the experiment‚ student dropped the flask containing 250 ml‚ 3 molar NaOH solution. Due to this 50 ml of solution out of 250 ml‚ had fallen on the floor. Thinking that teacher may punish him for this mistake‚ he replenished the left over solution with 50 ml of water. The new molarity of NaOH solution will be. (A) 2M (B) 3M (C) 2.5 M (D) 2.4 M 2.* Which of the following molarity values of ions in a aqueous solution

1. Briefly describe salt production from brine production to finished round cans. Salt is produce by drilling the surface for about 2‚400 feet below. Then‚ water is infused in this cave; thus‚ salt is dissolved with the water. The resulting brine is then pumped in the surface‚ boiled and when it evaporates‚ salt crystals will occur with some moisture but can be removed through the drying process. This happen continuously for about 6 weeks but there will come a point where output will reduce (normal
