How do you decide which of a group of solutions has the greatest concentration of hydroxide ions OH-?
To determine the pH of a range of solutions, you can use a pH meter, or a universal indicator.
Which of the following pH range is a strong base?
pH 14 is the strongest base and it is usually sodium hydroxide
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
Why does pH scale generally range from 0 to 14 in aqueous solutions?
The pH scale is used to measure how acidic or basic a substance is.
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.
What is the specific gravity of sodium hydroxide?
What is the pH of sodium hydroxide? What I determined from a wide range pH paper is that the pH of a .1 M solution of sodium hydroxide was that between 11 and 12.
What is the pH of sodium chloride solution?
The pH range of aqueous solutions of NaCl is 6.7 to 7.3 (MSDS)

What is the color of phenolphthalein in solutions with pH values ranging from 2 to 6?
A typical aqueous solution containing phenolpthalein is colorless within the pH range 2 - 6.
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).
Is ammonia dangerous?
It is a very powerful respiratory irritant, and could cause death in large doses. Annhydrous ammonia is especially dangerous, but strong solutions of aqueous ammonia are as well. The vapor is also flammable within a narrow range.
What is pH range for sodium chloride?
Sodium chloride solution is neutral.
In what region of visible range does the emission spectrum of sodium lie?
The emission of sodium lies in the yellow region
