**Calculating Approximate Alkalinity in Water Samples**To calculate the "approximate" alkalinity (expressed in milligrams per liter as CaCO₃) for a water sample, consider the following ion concentrations:- **Bicarbonate Ion Concentration**: 120 mg/L- **Carbonate Ion Concentration**: 15.00 mg/LThese concentrations represent the ions present in the water that contribute to its alkalinity, primarily through bicarbonate (HCO₃⁻) and carbonate (CO₃²⁻) ions.To compute the total alkalinity, you can use the equivalent weight conversions for each ion to CaCO₃ and add their contributions. The calculation involves converting the mass of each ion to an equivalent mass of calcium carbonate, a standard expression in water chemistry.

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

Question

**Calculating Approximate Alkalinity in Water Samples**

To calculate the "approximate" alkalinity (expressed in milligrams per liter as CaCO₃) for a water sample, consider the following ion concentrations:

- **Bicarbonate Ion Concentration**: 120 mg/L
- **Carbonate Ion Concentration**: 15.00 mg/L

These concentrations represent the ions present in the water that contribute to its alkalinity, primarily through bicarbonate (HCO₃⁻) and carbonate (CO₃²⁻) ions.

To compute the total alkalinity, you can use the equivalent weight conversions for each ion to CaCO₃ and add their contributions. The calculation involves converting the mass of each ion to an equivalent mass of calcium carbonate, a standard expression in water chemistry.
