The pH scale works like this:
1 being acidic, like lemon juice,
10 is basic, amonia
the lower the number the more acidic, higher numbers are basic and 7 is neutral
the stronger the base, the higher the number, which means a higher OH ion concentration. the stronger the acid, the lower the number, means a higher H3O ion concentration and a lower OH concentration.

What is the pH of a solution in which the concentration of hydrogen ion is greater than the concentration of hydroxide ion?
The pH of a solution with higher hydrogen ion concentration than hydroxide ion concentration will be less than 7, indicating an acidic solution. The exact pH value can be calculated using the formula pH = -log[H+].
Does a pH value signify certain number of hydrogen or hydroxide ions?
"pH" is a convention used as a convenience. It indicates how acidic (or basic, that is, alkaline) a solution is. It is the negative logarithm of the hydrogen ion concentration, usually the latter is expressed in moles (or millimoles) per liter. Moles per liter is, of course, what we call "molarity." pOH is used in the same way, indicating the concentration of hydroxyl ions. Generally, Concentration of hydrogen ions + the concentration of hydroxyl ions = 10-14 A neutral solution has equal numbers of H+ and OH-
Why when ammonia gas is bubbled into water the solution has such a high pH value?
When ammonia gas is bubbled into water, it reacts with water to form ammonium hydroxide, which is a strong base. The presence of ammonium hydroxide increases the concentration of hydroxide ions in the solution, leading to a high pH value. Ammonium hydroxide equilibrium with its ionic components NH4+ and OH- contribute to the alkaline nature of the solution.
Does an hydroxide ion give a pH value of 7 or more?
Yes, a hydroxide ion (OH-) contributes to an increase in pH above 7. It is a base that accepts a proton when dissolved in water, thereby increasing the concentration of hydroxide ions and raising the pH of the solution.
What is the accepted Ka value for sodium hydroxide?
The accepted Ka value for sodium hydroxide (NaOH) is not applicable, as NaOH is a strong base and completely dissociates in water. Instead, the equilibrium constant Kb (base dissociation constant) is typically used for strong bases. The Kb value for NaOH is approximately 1 x 10^-15.
What pH indicates that the most hydroxide ions are present?
The highest pH value in a group of such values indicates that the greatest concentration of hydroxide ions is present in the substance with the highest pH. This is true because a higher pH indicates a lower concentration of hydrogen ions, and the product of the molar concentrations of hydrogen and hydroxide ions must always be 10-14 at standard temperature and pressure in a mixture that is mostly water.
Does the pH scale indicate the consentration of hydrogen ions or hydroxide ions?
The pH scale indicates the concentration of hydrogen ions in a solution. A lower pH value indicates a higher concentration of hydrogen ions, while a higher pH value indicates a lower concentration of hydrogen ions.
Strongest base a pH can have?
Practically pH of 14 or 15 is the highest base value reachable, due to limits of max. concentration.
Which pH indicates the highest concentration of H3O?
The pure water has the pH=7; the concentrations of OH- and H3O + are equivalent.
Has a pH value equal to 7?
A pH value of 7 indicates a neutral solution, where the concentration of hydrogen ions is equal to the concentration of hydroxide ions. This means that the solution is neither acidic nor basic.
What is the best description for a solution with a hydroxide-ion concentration of 1x10-4 M?
A solution with a hydroxide-ion concentration of 1x10-4 M is considered basic because it has a higher concentration of hydroxide ions (OH-) relative to hydronium ions (H+). This concentration indicates a low pH value and a high alkalinity.
What has the highest pH value acetic acid or sodium hydroxide or sodium carbonate or sulphuric acid?
sodium hydroxide
Why are acidic substances lower in pH value than basic substances?
Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
Which ABG's value reflects the acid concentration in blood?
The pH value in an arterial blood gas (ABG) reflects the acid concentration in the blood. A lower pH indicates higher acid concentration (acidosis) and a higher pH indicates lower acid concentration (alkalosis).
What kind of solution would have a Kb value that is much greater then 1?
A solution with a Kb value much greater than 1 would be considered a strong base solution. This indicates that the base is more likely to fully dissociate in water, resulting in a high concentration of hydroxide ions and a higher pH. Examples include solutions of sodium hydroxide (NaOH) or potassium hydroxide (KOH).
What has the highest pH value dilute sodium bicarbonate or lemon juice or dilute sodium hydroxide solution?
dilute sodium hydroxide solution
How is the concentration of hydronium related to pH?
The concentration of hydronium ions ([H3O+]) is directly related to pH through the formula pH = -log[H3O+]. A lower pH value indicates a higher concentration of hydronium ions, and a higher pH value indicates a lower concentration of hydronium ions in a solution.
