What is the effect of dilution on the pH of strong acid?
Diluting a strong acid will generally have little effect on its pH. This is because strong acids completely dissociate in water to give H+ ions, so adding more water will not change the concentration of H+ ions significantly. Therefore, the pH of a strong acid solution remains relatively constant upon dilution.
If you add hydrochloric acid to water what effect would this have on the Hydrogen ion concentration?
Adding hydrochloric acid (HCl) to water increases the concentration of hydrogen ions in the solution. This is because HCl dissociates in water to form H+ ions and Cl- ions, thereby increasing the hydrogen ion concentration.
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.
What effect does dilution have on an acid?
The pH of the weak acids is lower than 7 (neutral) but higher than strong acids (which can be around 1). This is because pH is a measure of hydrogen ion concentration and weak acids only partially dissociate. It is a logarithmic scale, so pH=-log[H]+ so a larger concentration of hydrogen means a lower pH and a smaller concentration, a higher pH. Thus, when water is added to a weak acid, the concentration of hydrogen ions will decrease and the pH will become greater.
Will a substance - with a pH of 10 - have more hydrogen ions than hydroxide ions?
No. A pH of 10 is basic, which means, by definition, that it has more hydroxide ions than hydronium* ions. *Acids and bases are not measured with hydrogen atoms but the effect is the same.
How does the percentage of ionization change with its concentration?
The percent ionization of a weak electrolyte upon dilution is increased. This is in accordance with Le Chatelier's principle. Dilution causes the reaction to shift in the direction of the larger number of particles to counter the effect of the decreasing concentration.
What is the effect of dilution on viscosity of oil?
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.

Effect on H concentration in a solution in base?
In a base, the concentration of hydrogen ions (H+) decreases as they accept protons to form hydroxide ions (OH-). This leads to an increase in the concentration of hydroxide ions, resulting in a higher pH and a more basic solution.
When the ocean absorbs CO2 the pH of the ocean water rises. What is the effect of this process?

Which variable is the student's experiment described in the Prelab Activity designed to test?
The student's experiment in the Prelab Activity is designed to test the effect of changing the concentration of hydrogen peroxide on the rate of enzyme activity in the enzyme catalase. This involves manipulating the independent variable (concentration of hydrogen peroxide) to observe its impact on the dependent variable (rate of enzyme activity).
