What does Ca and HCO3 make?
CaCO3, which is calcium carbonate.
Alkalinity of water cannot be due to the simultaneous presence of OH CO3 and HCO3 Give reason?
The alkalinity of water is primarily due to the presence of bicarbonate (HCO3⁻), carbonate (CO3²⁻), and hydroxide (OH⁻) ions, which can neutralize acids. However, if CO3²⁻ and HCO3⁻ are present simultaneously without the corresponding acid or base to balance them, they would neutralize each other, leading to a stable pH and effectively reducing the overall alkalinity. In essence, for alkalinity to be significant, these ions must exist in a way that allows them to contribute to acid neutralization rather than cancel each other out. Thus, the concurrent presence of all three ions would not result in high alkalinity.
What kind of reaction is represented here ca(hco3)2 caco3?
no , is the chemical formula by benda Benjamen
What is the difference between HCO3- and HCO3plus?
HCO3- is a anion (bicarbonate); HCO3+ don't exist.
What types of alkalinity?
Alkalinity primarily refers to the capacity of water to neutralize acids and is commonly categorized into three types: bicarbonate (HCO3-), carbonate (CO3^2-), and hydroxide (OH-). Bicarbonate is the most prevalent form in natural water systems, while carbonate becomes more significant at higher pH levels. Hydroxide ions contribute to alkalinity when pH levels are extremely high. Together, these forms help buffer pH changes in aquatic environments.
What does Ca and HCO3 make?
CaCO3, which is calcium carbonate.
Why alkalinity is measured as CaCO3 Eq?
Alkalinity is measured as CaCO3 Eq (equivalents) because it represents the amount of acid needed to lower the pH of the water to a certain level based on the buffering capacity provided by carbonate ions. Expressing alkalinity in terms of CaCO3 Eq standardizes the measurement and makes it easier to compare between different water samples or systems.
What are thermo reactions?
•dissolution of carbonates: -CaCO3 + H+à Ca2+ + HCO3-
What is the equation calcium bicarbonate plus calcium carbonate plus carbon dioxide gas plus water?
The equation is H2O + CO2 + CaCO3 --> Ca(HCO3)2
What kind of reaction is represented here ca(hco3)2 caco3?
no , is the chemical formula by benda Benjamen
What is thermo reactions?
•Individual reactions may be repetitive but are different: •Consider dissolution of carbonates: -CaCO3 + H+ > Ca2+ + HCO3-
What is the difference between temporary hard water and permanent hard water?
it is caused due to the salts of calcium and magnesium carbonates and bicarbonates. CaCO3, MgCO3, Ca(HCO3)2, Mg(HCO3)2
I was recently at the fish store and the salesman said that the reason for the high alkalinity in my tank was due to shells made of calcium. Why would Calcium be making my water more basic?
# The shells aren't made of calcium, they're made of calcium carbonate. # Calcium carbonate is the salt of a strong base and a weak acid, and is therefore weakly alkaline. I understand that you can make CaCO3 by the following process: HCO3 + CaOH => CaCO3 +H2O But once you have made CaCO3 ( a slightly alkaline salt) from the acid and base, what is happening to the CaCO3 in the H2O that is making the water more basic? In other words, how can CaCO3 have anything to do with the lone OH- ions present in the water?
What is the correct unit for alkalinity?
The correct unit for alkalinity is usually expressed in milligrams per liter (mg/L) or parts per million (ppm) of calcium carbonate (CaCO3) equivalent.
What is the chemical equation for the decomposition of calcium hydrogen carbonate?
the chemical equation for the decomposition of calcium hydrogen carbonate is given below.Ca(HCO3)2(aq) → CO2(g) + H2O(l) + CaCO3(s).It is a balance chmeical reaction.
How do you calculate the alkalinity?
Alkalinity can be calculated by titrating a water sample with a strong acid until the pH reaches a specific endpoint. The amount of acid required to reach this endpoint is used to determine the concentration of alkalinity in the water sample. Typically, alkalinity is expressed in units of milligrams per liter (mg/L) of calcium carbonate (CaCO3).
Calcium bicarbonate formula?
CaHCO3- Calcium bi carbonate. CaCO3- Calcium carbonate
