Why is pH used instead of H+?
Precisely, the definition of pH is –log(aH+) i.e.
negative logarithm of activity of H+, but people used to define pH as negative logarithm of concentration of H+.
For highly diluted solution, activity coefficient is become unity, so now, we can write pH = —log(C H+) or = —log[H+]..
Is pH above 14 possible?
A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm−3, has a pH of 14. Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
What is the pH of 0.01 m Naoh?
For example, the pOH at a 0.01 M solution of sodium hydroxide is 2, the pH of the same solution must be 14-2 = 12.
What is the strongest base in the world?
The Strongest Base Ever Made. The methyl anion H3C– was the strongest known base for 30 years, until Tian and colleagues made the lithium monoxide anion in 2008, which has held the record since.
Where is H+ on the pH scale?
“pH” is an abbreviation for the French expression, “Pouvoir Hydrogene,” meaning “the power of Hydrogen.” It measures the H+ ion concentration of substances and gives results on a scale from 0 to 14. Water that contains equal numbers of H+ and OH- ions is considered neutral (pH 7).
Which solution has the highest concentration of H+ ions?
On the pH scale, the number which has the highest concentration hydrogen ions is generally 0. This represents a solution with a hydrogen ion… On the pH scale, the number which has the highest concentration hydrogen ions is generally 0.
Which solution has the greatest number of hydrogen ions?
Answer Expert Verified. The Answer is option B. pH is a scale for measuring either the solution is acidic or basic or neutral. In another way we can also say that pH is the measurement of concentration of hydrogen ions.
What pH has the fewest number of H+ in the solution?
A pH of 2 therefore, indicates ten times fewer hydrogen ions than a pH of 1, pH 3 has ten times fewer hydrogen ions than pH 2 and one hundred times fewer hydrogen ions than pH 1.
Can acid destroy a diamond?
No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance. Hope this has been helpful!
Does an acid have more H+ ions?
An acid is a solution with more H+ ions than OH- ions. An acid is any compound that yields hydrogen ions (H+) or hydronium ions (H3O+) when dissolved in water. Hydronium ions – are the combination of H+ ions and H2O molecules.
What two solutions have more H+ ions than OH ions?
Solutions have more H+ ions than OH- ions, if the solutions are acids. A solution is an acid if its pH value is less than 7.
Is pH more than 14 possible?
It is common that the pH scale is argued to range from 0-14 or perhaps 1-14, but neither is correct. … One can go somewhat below zero and somewhat above 14 in water, because the concentrations of hydronium ions or hydroxide ions can exceed one molar.
How would an increase in hydrogen ions change the pH of blood?
The increase in H+ leads to a decrease in pH (that is, the blood becomes more acidic). If the amount of CO2 is decreased, the reaction can run in reverse. That is, the HCO3– binds the free H+ ions to produce carbonic acid and convert it into CO2. The blood becomes more alkaline.
Is H+ A pH?
Water that contains equal numbers of H+ and OH- ions is considered neutral (pH 7). If a solution has more H+ than OH- ions, it is considered acidic and has a pH less than 7.

What pH is dangerous?
The danger of more acidic water – when the pH is less than 6.5 – is that it can leach metals from the well and from the pipes that bring you water. These metals include lead, manganese, copper and iron, and they can be toxic in large amounts. So acidic water obviously poses a health risk.
Which is more dangerous acid or base?
Explanation: Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.
Does more H+ mean higher pH?
High concentrations of hydrogen ions yield a low pH (acidic substances), whereas low levels of hydrogen ions result in a high pH (basic substances). The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1).
