Which of the following is true about bases they tend to decrease PH solution or they release hydroxide ions in solutions?
Technically, neither is entirely true. Bases will not decrease the pH, but neither do they always release hydroxide. For example, ammonia and the amines are basic, but this is because they remove hydronium, not because they add hydroxide. They release hydroxide ions in solution.
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.
Is it true that An acidic solution has a very high concentration of OH ions?
No it is false -it has a high concentration of H+ ions
Is an acid is any compound that forms H plus ions in solution true?
Not all the time. Only acids that react with metals will give of Hydrogen (H) Acid + Metal --> Salt + Hydrogen
A substance that forms hydroxide ions in a water solution is a base?
Yes, that is correct. Bases are substances that release hydroxide ions (OH-) when dissolved in water, leading to an increase in the concentration of hydroxide ions in the solution. Examples of bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
Is an acid a substance that produces hydroxide ions in a water solution?
False

The concentration of hydrogen ions in solution is the pH of the solution the answer has to be either true or false?
True. The concentration of hydrogen ions in a solution directly determines the pH of the solution. A lower concentration of hydrogen ions results in a higher pH, while a higher concentration of hydrogen ions results in a lower pH.

What is true about the relative concentrations of hydronium and hydroxide ions in an acid solution?
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
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.
The reason pure water has a pH of 7 is that there is the same concentration of hydrogen and hydroxide ions on the self-ionization of water?
Pure water has a pH of 7 because it is neutral, with equal concentrations of hydrogen ions (H+) and hydroxide ions (OH-) due to the self-ionization of water. This balance of ions gives rise to a pH level of 7, indicating a neutral solution.
A base is a substance that forms hydroxide ions in a water solution.?
A substance that forms hydroxide ions in a water solutoin is a base -- TRUE -- apex:)
What is true about a hydroxide ions?
Hydroxide ions are anions with the chemical formula (OH)-.
