The pH increases. There are two ways to think about this. First, adding hydroxide ions is the same as adding a base, and a base will cause the pH of a solution to become more basic, i.e. increase. Second, hydroxide ions will react with hydrogen ions in the solution to neutralize them, decreasing the concentration of hydrogen ions. Since the pH scale is a negative logarithmic scale, a decrease in the concentration of hydrogen ions means an increase in pH.
What else can I help you with?
Which molecule can increase the concentration of hydrogen ions in a solution and therefore is an organic acid?
An example of a molecule that can increase the concentration of hydrogen ions in a solution and is considered an organic acid is acetic acid. Acetic acid is a weak organic acid that dissociates in solution to release hydrogen ions, contributing to increased acidity.
When some aci is added to a solution of an alkali will the pH value of the solution increase or decrease explain?
When an acid is added to a solution of an alkali, the pH of the solution will decrease. This is because the acid will increase the concentration of hydrogen ions, leading to a more acidic solution.
What effect does dilution have on the hydrogen ion concentration of sulphuric acid?
Diluting sulfuric acid decreases the hydrogen ion concentration because the concentration of sulfuric acid molecules in the solution decreases. As a result, the overall hydrogen ion concentration decreases in the diluted solution.
Would an increase in the concentration of the sulfuric acid increase the rate of hydrogen production?
Yes, increasing the concentration of sulfuric acid will increase the rate of hydrogen production in a reaction where it acts as the electrolyte in a setup like electrolysis of water. This is because a higher concentration of sulfuric acid provides more ions in the solution, allowing for more efficient ion conduction and thus faster hydrogen generation.
What substance yields a hydrogen ion when placed in a water solution?
An acid is a substance that yields a hydrogen ion (H+) when placed in a water solution. Acids increase the concentration of hydrogen ions in a solution, leading to a decrease in pH. Examples of common acids include hydrochloric acid (HCl) and acetic acid (CH3COOH).
Which substances decrease the H ion concentration in an solution?
An acid increase the hydrogen ion concentration in a solution.

What does an increase in the concentration of hydrogen ions in a solution cause?
Two things: and increase both in i) the caustic powers resulting from the dissolution of an acid in water: due to the fact that H+ [hydrogen ions] are what makes an acid An Acid; and ii) an increase in the readings on the pH - level of acid/base - Scale.
What acts to increase the hydrogen ion concentration of a solution?
An acid.An acidic compound.

What solution is based on its concentration of the element hydrogen?
A solution based on its concentration of the element hydrogen is typically referred to as an acid or a hydrogen ion solution. Acids, when dissolved in water, release hydrogen ions (H⁺), which increase the solution's acidity. The pH scale is used to measure this concentration, with lower pH values indicating higher hydrogen ion concentrations and thus stronger acids.
What is the process for calculating the pH of a strong acid solution?
To calculate the pH of a strong acid solution, you can use the formula pH -logH, where H represents the concentration of hydrogen ions in the solution. For a strong acid, the concentration of hydrogen ions is equal to the concentration of the acid. Simply take the negative logarithm of the hydrogen ion concentration to find the pH value.
Is a solution of ph2 a weak acid?
No, a solution with a pH of 2 is considered a strong acid because it has a high concentration of hydrogen ions. The lower the pH value, the higher the concentration of hydrogen ions and the stronger the acid.
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.
