What are non-pourous rocks?
These are rocks that are highly compacted, having little or no pore spaces within their grains. They do not readily allow the passage of water through them.
What are the consequences of low alkalinity in boiler water?
corrosion problems because of the acidity as well as the other water treatments may not work if the alkalinity is out of target
How water can cause rocks to weather?
They make the rock fly to space
Write a summary of the the three types of rocks and how they are formed?
igneous rocks are formed by cooling lava from volcanos. Obsidian is an igneous rock. Sedimentary rocks are formed by particles being deposited by water. Sandstone is a sedimentary rock. Metamorphic rocks are formed when heat, pressure, and chemical reactions change existing rocks. Granite is a metamorphic rock.
How do you find alkalinity in water?
pH paper or a pH probe
Why do you inject phosphate in boiler feed water?
To control the alkalinity of boiler water which is directly related to pH control. Too alkaline will cause stainless steel to brittle while too low alkalinity will cause corrossion.
What causes low alkalinity?
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.
Which are not minerals?
Water and air are not minerals; granite, porphyry, clay, pumice are rocks, not minerals.
What causes low total alkalinity?
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.
Difference between phenolphthalein alkalinity and and total alkalinity?
phenolphthalein alkalinity is due to hydroxide n carbonate salts in water...nd total alkalinity is mainly due to bicarbonate salts in water..
Can rocks float?
Pumice floats in water, but for other rocks you'd need to find a fluid that's more dense than the rocks to float them in. For example, mercury is almost 6 times as dense as granite, so a lump or slab of granite will ride right up there high in a pool of mercury.
Does high alkalinity cause cloudy water?
it might not be to high of a ph but could be a very hot water in a cooler room that is how some pools r cloudy
How do you raise the pH level in the pool?
there are two primary chemicals on the merket used to do this. 1.) soda ash usually packaged under the name pH rise or pH increaser. 2.)sodium bicarbonate usually packaged under the name alkalinity rise or alkalinity increaser. both of the above chemicals will increase both the pH and Alkalinity of the swimming pool water. always make sure your alkalinity is balanced before making any pH adjustment. it is also important to understand pH and alkalinity always move together and in the same direction. so a pH adjustment will cause a change in your alkalinity level the same way a alkalinity adjustment will cause a change in your pH. when you increase pH, alkalinity will also increase when you decrease pH, alkalinity will also decrease when you raise alkalinity, pH will also rise. always dose chemicals according to the directions on the chemical container and the volume of water you are treating.
What cause rocks in a stream to be smooth?
flowing water
If you have a good alkalinity with mains water what would lower it in a swimming pool with out the addition of chemicals.?
Add rain water this has very low alkalinity
You want to change the alkalinity of your hot tub water will muriatic acid be your best choice?
Muriatic acid is what is used to reduce alkalinity in water.
How does matter in rocks change to matter in water?
Water can dissolve some of the matter found in rocks. Also, through the alternating processes of freezing and melting, water can cause pieces of rocks to fall into it.
