What pH do Alkalis have?

Any aqueous solution that has a pH value greater than 7 can be considered alkaline. A strongly alkaline aqueous solution usually has a pH of at least 10, and aqueous solutions of very strong alkalies can have a pH range above 13.


Which of the following pH range is a strong base?

pH 14 is the strongest base and it is usually sodium hydroxide


How do you decide which of a group of solutions has the greatest concentration of hydroxide ions OH-?

Determine the concentration of hydroxide ions by looking at the molarity of the base in the solution. A higher molarity of the base will result in a greater concentration of hydroxide ions. Use stoichiometry to calculate the concentration of hydroxide ions based on the balanced chemical equation for the reaction.


Examples of the pH scale?

Strong acid, periodic acid HIO4, pH range -0.5 to +2.0 Weak acid, acetic acid CH3COOH, pH range 2.5 to 5.5 Neutral (practically): pH range 6.5 to 7.5 Weak basic, ammonia NH3(aq), pH range 8.0 to +11.0 Strong basic, (sodium) hydroxide (Na+)OH-, pH range 12.0 to 14.5


How does the Bronsted-Lowry definition of an acid differ from the Arrhenius definition of an acid?

The Bronsted-Lowry definition includes substances that donate protons, not just in aqueous solutions like the Arrhenius definition. This allows for a broader range of acidic substances to be classified. Additionally, Bronsted-Lowry acids can exist in non-aqueous environments, unlike Arrhenius acids which are limited to aqueous solutions.

Does alkaline contain dissolved sodium hydroxide?

Alkaline solutions may contain dissolved sodium hydroxide, but not always. Alkaline substances can refer to a wide range of compounds that have a pH greater than 7, including those that do not contain sodium hydroxide.

What is the pH of sodium chloride solution?

The pH range of aqueous solutions of NaCl is 6.7 to 7.3 (MSDS)


Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?

Phenolphthalein is chosen as a suitable indicator for sodium hydroxide because its color change occurs in the pH range around 8.2 to 10.0, which is close to the pH range of the equivalence point for the titration of a strong base like sodium hydroxide with a strong acid. This allows for a sharp and easily detectable color change at the endpoint of the titration.


Why do biologist use solutions that are aqueous?

Biologists use aqueous solutions because water is the most common solvent in living organisms. Aqueous solutions are able to dissolve a wide range of molecules and ions, making it easier to study biological processes and reactions. Additionally, many biological reactions occur in aqueous environments within cells and tissues.

What are the industrial uses of sodium hydroxide?

Sodium hydroxide is used in a wide range of industrial applications, including in the production of paper, textiles, soaps, and detergents. It is also used in water treatment processes, petroleum refining, and as a cleaning agent in industries such as food processing and metal cleaning. Additionally, sodium hydroxide is used in the manufacture of various chemicals and pharmaceuticals.


What happens to the original sodium and chlorine after the chloro alkali process?

Chlor-alkali process is really a whole range of processes associated with salt (sodium chloride) and sodium and chlorine. The primary products are sodium and chlorine. Chlorine has almost limitless uses from simple bleach to plastics manufacture. Sodium is basically a byproduct but generally finds use once converted to caustic soda (sodium hydroxide).
