Why does pH scale generally range from 0 to 14 in aqueous solutions?
The pH scale ranges from 0 to 14 in aqueous solutions because it corresponds to the concentration of hydrogen ions (H+) in the solution. A pH of 7 is considered neutral, with equal concentrations of H+ and OH- ions. Values below 7 indicate an acidic solution with higher H+ concentrations, while values above 7 indicate a basic solution with lower H+ concentrations.
The pH scale is used to measure the amount of what atom?
The pH scale measures the amount of available H+ ions. Specifically pH=-log10[H+]
Compare acidic and basic solutions in tems of their plus H ion and -OH ion concentrations?
Acidic solutions contain higher concentrations of H+ ions than pure water and have pH values below 7. Strong acids tend to have pH values that range from 1 to 3. The hydrochloric acid produced by the stomach to help digest food is a strong acid.
How is the pH scale used to determine if a substance is acidic or basic?
The pH scale measures the concentration of hydrogen ions in a solution. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity (basicity). The closer the pH value is to 7, the more neutral the solution is.
Acidic solutions are those that contain an excess of?
Acidic solutions contain very high concentrations of hydrogen ions. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.

How are the concentrations of hydronium ions and hydroxide ions in aqueous solutions related?
The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.
The pH scale is used to measure the amount of what atom?
The pH scale measures the amount of available H+ ions. Specifically pH=-log10[H+]
What type of solution contains a higher hydrogen concentration?
Acid solutions contain higher concentrations of hydrogen ions (hydronium ions).
Is it true that The pH scale measures the concentration of hydroxide ions?
No, pH measures the concentration of hydrogen ions. pOH would measure hydroxide concentration.
What scale measures the concentration of hydrogen ions?
The scale that chemists use to describe the concentration of hydronium ions in a solution is know as the pH Scale
Do basic solution have h plus ions?
nah man. them acids has them lot. the H+ ions that is. but these basic solutions donate a massif amount of OH- ions compared to H+ ions when added to an aqueous solution.
Why glucose solution cannot conduct electricity?
Glucose does not dissociate into charged ions in water solution, and the only water solutions with high conductivity are those with substantial concentrations of charged ions, such as the solutions of most salts, acids, and bases.

What are solutions that have more OH- then H ions called?
A basic solution has greater concentrations of OH- than H+ ions. The opposite is acidic. An easy mnemonic device for this is that you want to get an A+ not a B-.
Why do some solutions have fair conductivity?
Conductivity in solutions is all about charge carriers (ions). Ions (like sodium and chlorine ions - Na+ and Cl-) in solutions make it conduct pretty well. Sugar dissolved in water doesn't really make a solution that wants to conduct. Solutions with "fair" conductivity have ion (charge carrier) concentrations that are "modest" to "fair" and that is what make them "fair" conductors.
