Normal lake waters, in contrast, have relatively neutral pH values near 7. The crater lake at El Chichon volcano in Mexico had a pH of 0. The acid waters of these lakes Why is our porcelain sink stained brown?
The brown stain is from a large amount of iron in your water. It is closely related to simple rust that you see on metal, which is iron oxide. Your water probably comes from groundwater that filtered through rocks containing iron-rich minerals on its way to the well. Why does my drinking water look cloudy sometimes?
Once in a while you get a glass of water that looks cloudy; maybe milky is a better term. After a few seconds, it miraculously clears up! The cloudiness is due to tiny air bubbles in the water. Like any bubbles, the air rises to the top of the water and goes into the air, clearing up the water. The water in the pipes coming into your house might What can cause our water to have an earthy odor or to smell like rotten eggs?
Naturally-occurring organic compounds are created when plant material decays in lakes and reservoirs. Those organic compounds frequently cause musty, earthy odors, especially toward the end of summer.
The odors can be objectionable, but generally are not harmful to health. However, odors can be caused by other constituents as well, so you might Why are some lakes full of algae and thick plants? Plants naturally grow in and around lakes, but sometimes lakes and ponds can get an overgrowth of plants, algae, or bacteria. In many cases, humans are responsible.
Chemicals that are used on lawns and in agriculture like nitrogen and potassium wash into our water systems. How does mine drainage occur? Mine drainage is formed when pyrite an iron sulfide is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.
The acid runoff further dissolves heavy metals such as copper, lead, and Filter Total Items: 8. Hi Chris. If I wanted to create a CO2 generator would it be more productive to use hydrochloric acid with limestone or calcite marble?
The idea is to use a bucket with a couple of inches of aforementioned rocks covered with water and some added hydrochloric acid. If I used ml of hydrochloric acid how much CO2 would that produce? The concentration of the acid determines how many protons hydrogen ions it can donate to react with the marble.
You need 2 hydrogen ions per carbonate group. The stronger the acid, the more protons and the more CO 2 you can make:. Sorry forgot to mention that. I want to create water soluble calcium for agriculture. Since its so expensive I wanted to try using cheap limestone and acid to create my own. Does the hydrogen carbonate precipitate to the bottom, while pure calcium stays dissolved in the water? Is there a way to separate them so I'm just left with calcium?
How long does it take for the reaction between sulphuric acid in acid rain and calcium carbonate to proceed? There are a lot of factors. Sulphuric acid reacting with calcium carbonate will actually produce calcium sulphate, which is insoluble; this will coat the carbonate surface, reducing access to the carbonate by fresh hydrogen ions. So the reaction will initially appear to go fast, then very slowly once the sulphate layer builds up Limestone in rock form is not available sor some reason in my country now a days.
We fill tank with water and hcl and limestone rock in tanks to neutralize hcl We have calcium carbonate in powder form can we neuterlize hcl with it? Kindly please help me with a solution to neutralize hcl. We make calcium stearate. Why not just pop your teacher's name and email address in the box and we'll send the homework answer directly to them on your behalf, to save you the bother since we're already being asked to do the homework itself for you What type of chemical reaction is it?
I was thinking it was a neutralization reaction, although salt is not produced. It is a neutralisation reaction, and there is a resulting salt: calcium bicarbonate - Ca HCO 3 2 aq.
I have a hundred pounds of common opal covered in what appears to be limestone. Is there a way to dissolve it? I'm stuck on this question and I need to prove how you can tell that the gas limestone is giving off when added to acid is carbon dioxide can someone tell me how you prove it please?
The classic test for carbon dioxide is that, when bubbled through limewater, the solution turns milky. This is because the limewater - which is calcium hydroxide - Ca OH 2 - reacts with carbon dioxide to form calcium carbonate - CaCO 3 which is insoluble; this precipates as fine particles, which impart a milkiness to the solution.
Limestone - calcium carbonate, CaCO3 - dissolves and at a low rate. Sodium carbonate Na2CO3 dissolves faster than limestone; it reacts with acids in a chemical reaction, producing carbon dioxide. Limestone is calcium carbonate CaCO 3. What is an evaporite and how is it formed?
