Why you consider calcium carbonate as a standard to measure water hardness?
Calcium carbonate is used as a standard to measure water hardness because it is a common component of hard water and its level can be easily measured using titration methods. The amount of calcium carbonate in water is directly related to the overall hardness of the water, making it a reliable standard for comparison and analysis.
Why does limescale form on the inside of kettles?
put simply limescale is caused by the reversal of the reaction that takes place to make hard water that contains high levels of calcium and magnesium when the reaction is reversed this is what causes limescale. to test for hard water use a block of standard soap and if the soap makes scum the water is hard water if it creates bubbles it is soft water
What is EDTA titration of Water?
It one of the titrations method to determine the permanent and temporary hardness of water. Procedure; step 1: standardise the edta solution step 2: titrate against the hard water mixed with ebt until the colour changes from wine red to blue. Then we can caluclate the normality using the formula (n1) *(v1)=(n2)*(v2). Posted by Krishna kanth yenumula.
Does hard water have a distinct smell?
No, hard water does not have a distinct smell.
Does boiling hard water make it soft?
Boiling hard water does not make it soft. Boiling water only removes some impurities and kills bacteria, but it does not change the mineral content that makes water hard. To soften hard water, a water softener system is needed.

What is standard hard water?
Standard hard water typically contains high levels of minerals such as calcium and magnesium. These minerals can cause limescale buildup in pipes and appliances, reducing their efficiency and lifespan. Water hardness is often measured in grains per gallon or parts per million of mineral content.
Can you take water into Disneyland?
Yes, as long as they are not glass bottles or carried in hard sided coolers.
Where does kettle limescale come from?
limescale is caused by the reversal of the reaction that takes place to make hard water that contains high levels of calcium and magnesium when the reaction is reversed this is what causes limescale. to test for hard water use a block of standard soap and if the soap makes scum the water is hard water if it creates bubbles it is soft water
What was carried out the plane in Die Hard 2?
peanuts
What does hard water do?
Hard water refers to water (H2O) that contains a relatively high concentration of dissolved mineral salts, such as magnesium and calcium. These dissolved salts are often undesirable, as they can precipitate as insoluble solids, causing mineral buildup.
How much memory on a standard hard drive?
Hard drives come in many standard sizes, ranging from a few megabytes to over a terrabyte.
Why cant a standard hard drive be used in a mac?
Macs only use standard hard drives such as the 7200-rpm Serial ATA hard drive found in many Macs.
How can an expensive guitar be carried?
Hard casing. when delivering in a vehicle loosen the strings.
How could you use a flame test to distinguish between hard and soft water?
A flame test is not typically used to distinguish between hard and soft water, as it primarily identifies the presence of certain metal ions based on their characteristic colors when heated. To differentiate hard water, which contains dissolved minerals like calcium and magnesium, from soft water, one would more commonly use tests for these ions or observe the formation of soap scum. Instead of a flame test, titration with a soap solution or a simple qualitative test for the presence of calcium and magnesium would be more effective.

What happen when standard hard water is boiled?
Lime scale will eventually coat the inside of the kettle. Unless this layer of lime scale is regularly removed, the efficiency of the kettle to boil water fast is impaired.
