say for example the equilibrium I2(aq)+H2O(l)-----HOI(aq)+I(aq)+H(aq)
Think Lechatlier principle... addition of NaOH will cause the H ions to react with the OH ions to cause more water (more reactants) increase in reactants shifts the equilibrium in the FORWARD direction to form MORE H+ to restore the equilibrium

Which type of chemical substance lowers the H concentration in a solution?
A base or alkaline substance lowers the H (hydrogen ion) concentration in a solution. Bases can accept or remove hydrogen ions from the solution, increasing the concentration of OH- ions and thereby reducing the concentration of H+ ions. Examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).
What effect does NA plus have on pH?
The addition of sodium hydroxide (NaOH) increases the pH of a solution by releasing hydroxide ions (OH-) which combine with hydrogen ions (H+) to form water. However, the addition of sodium ions (Na+) alone does not directly impact the pH of a solution.
Does NaOH contains H plus ions?
No, NaOH (sodium hydroxide) does not contain H+ ions. When NaOH dissolves in water, it dissociates into Na+ and OH- ions, with OH- being the hydroxide ions that can accept H+ ions to form water in a chemical reaction.
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.
A solution of malonic acid h2c3h2o4 was standardized by titration with 0.1000 M Naoh solution if 20.76 ml of the naoh solution were required to neutralize completely 13.15 ml of malonic acid solution?
The balanced chemical equation for the reaction is H₂C₃H₂O₄ + 2NaOH → Na₂C₃H₂O₄ + 2H₂O. By stoichiometry, 1 mol of malonic acid reacts with 2 mol of NaOH. From the given data, the concentration of the malonic acid solution can be calculated to be 0.133 M.
What is the effect of dilution on the pH of NaOH?
Dilution of NaOH will result in a decrease in pH. This is because as NaOH is diluted, the concentration of hydroxide ions (OH-) decreases, leading to a decrease in alkalinity and an increase in acidity, resulting in a lower pH.
What is the concentration of hydrogen ions in a 0.0010M aqueous solution of NaOH?
The concentration of hydrogen ions in a 0.0010M aqueous solution of NaOH is 1.0 x 10^-11 mol/L, as NaOH dissociates in water to form Na+ and OH- ions. In this process, there are no hydrogen ions produced.
How does the concentration of H plus and OH- ions determine pH?
The concentration of H+ ions in a solution determines its acidity; the higher the concentration of H+ ions, the lower the pH. The concentration of OH- ions in a solution determines its alkalinity; the higher the concentration of OH- ions, the higher the pH. pH is a logarithmic scale that represents the concentration of H+ ions in a solution.
What amount of NaOH is needed to increase the pH from 8 to 10?
To calculate the amount of NaOH needed to increase the pH from 8 to 10, you need to consider the volume of the solution and the concentration of NaOH. Using the equation pH = -log[H+], you can determine the concentration of H+ ions at pH 8 and pH 10, then calculate the amount of NaOH needed to neutralize the difference in H+ ions to reach pH 10.
How do you find out the pH of sodium hydroxide?
To find out the pH of sodium hydroxide, you can perform a pH test using a pH meter or pH paper. Sodium hydroxide is a strong base, so it will have a high pH value, usually around 12-14, depending on its concentration.
Which type of chemical substance lowers the H concentration in a solution?
A base or alkaline substance lowers the H (hydrogen ion) concentration in a solution. Bases can accept or remove hydrogen ions from the solution, increasing the concentration of OH- ions and thereby reducing the concentration of H+ ions. Examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).
What is the H in a 0.25M solution of NaOH (strong)what is OH-?
In a 0.25M solution of NaOH, the concentration of hydroxide ions (OH-) is also 0.25M. This is because NaOH dissociates completely in water to form Na+ and OH- ions. OH- represents the hydroxide ion in solution.
What effect does NA plus have on pH?
The addition of sodium hydroxide (NaOH) increases the pH of a solution by releasing hydroxide ions (OH-) which combine with hydrogen ions (H+) to form water. However, the addition of sodium ions (Na+) alone does not directly impact the pH of a solution.
When Na OH is added to water the hydrogen concentration increases what can you conclude about Na OH?
When NaOH is added to water, it dissociates into Na+ and OH- ions. The increase in hydrogen concentration is due to the OH- ions reacting with water to form more H2O molecules, shifting the equilibrium towards formation of additional H+ ions. This suggests that NaOH is a strong base that can increase the hydrogen ion concentration in a solution.
What is the formula for aldehyde plus NaOH?
The reaction of an aldehyde with NaOH forms sodium salt of the corresponding carboxylic acid. The general equation is: Aldehyde + NaOH -> Sodium salt of carboxylic acid + H₂O.
Does NaOH contains H plus ions?
No, NaOH (sodium hydroxide) does not contain H+ ions. When NaOH dissolves in water, it dissociates into Na+ and OH- ions, with OH- being the hydroxide ions that can accept H+ ions to form water in a chemical reaction.
How do the concentrations of hydrogen ion and hydroxide ion determine whether a solution is acidic basic or neutral.?
If the concentration of hydrogen ions (H+) is greater than the concentration of hydroxide ions (OH−), the solution is acidic. If the concentration of hydroxide ions (OH−) is greater than the concentration of hydrogen ions (H+), the solution is basic. If the concentrations of hydrogen ions (H+) and hydroxide ions (OH−) are equal, the solution is neutral.
