Which substances decreases the H ion concentration in a solution?
Bases, anything with the OH- ion in the formula.
Why the acidic character increases with the decrease in pH?
The acidic character increases with decrease in pH because the pH and acidity are both dependent on the hydrogen ion concentration, with pH being the negative log of the hydrogen concentration. So, at the concentration of H+ increases, the negative log of the H+ concentration decreases.
Which kind of compound increases the hydrogen ion concentration in a solution?
Acids increase the hydrogen ion concentration in a solution.
What is the pH solution defined as what of the hydrogen ion concentration?
The pH is a measure of the activity of the ion H+ in a solution.
What is the pH of a solution that has a hydrogen ion concentration of 110?
A hydrogen ion concentration of 110? 110 what? Or is that supposed to be 1x101
Which substances decrease the hydrogen ion concentration in a solution?
Adding a base the hydrogen concentration decrease.
Which substances increase the H ion concentration a solution?
acids
Will the pH increase decrease or remain the same if the concentration of weak bases increases?
If the concentration of weak bases increases, the pH of the solution will increase. Weak bases accept protons in solution, leading to a decrease in hydrogen ion concentration and an increase in hydroxide ion concentration, which in turn raises the pH.
Which substances decreases the H ion concentration in a solution?
Bases, anything with the OH- ion in the formula.
How do the concentrations of hydrogen ion and hydroxide ion determine whether a solution is acidic basic or neutral.?
acids are substances that release their hydrogen ion(s) while bases grab hydrogen ions to themselves. SO, adding acids will increase the H+ concentration while adding bases will decrease the H+ concetration of the solution. This would be considered a direct effect.
Why the acidic character increases with the decrease in pH?
The acidic character increases with decrease in pH because the pH and acidity are both dependent on the hydrogen ion concentration, with pH being the negative log of the hydrogen concentration. So, at the concentration of H+ increases, the negative log of the H+ concentration decreases.
What happens to the hydroxide ion concentration in aqueous solutions when you increase the hydrogen ion concentration by adding an acid?
The hydroxide ion concentration would decrease in response to the increase in hydrogen ion concentration. This is due to the neutralization reaction that occurs between the added acid (which releases H+ ions) and the hydroxide ions (OH-) present in the solution.
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
At a pH of 7 what is true a The hydroxide ion concentration equals the hydronium ion concentration b The concentration of the acid equal the concentration of the conjugate base?
At a pH of 7, both statements are true. The hydroxide ion concentration equals the hydronium ion concentration in a neutral solution with pH 7. Additionally, in a neutral solution, the concentration of the acid equals the concentration of the conjugate base since the solution has an equal balance of H+ and OH- ions.
Which kind of compound increases the hydrogen ion concentration in a solution?
Acids increase the hydrogen ion concentration in a solution.
What happens to the hydronium ion concentration if you increase the hydroxide ion concentration?
If you increase the hydroxide ion concentration, the equilibrium will shift towards the formation of more water molecules. This will result in a decrease in the hydronium ion concentration.
If a solution is considered to be basic is true about the hydroxide ion concentration?
If a solution is considered basic, then the hydroxide ion concentration is higher than the hydrogen ion concentration. This means that the pH of the solution is greater than 7. The presence of hydroxide ions contributes to the alkaline properties of the solution.
