# What Is The Maximum PH Value?

## What pH is dangerous?

Water with a very low or high pH can be a sign of chemical or heavy metal pollution.

Water that doesn’t fall in the “safe” pH range of 6.5 to 8.5, particularly if it’s alkaline, isn’t necessarily unsafe..

## Why is my pH so high?

An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. … A higher pH level can also be caused by a sudden rise in temperature of the water. However, much more important than the causes are the effects of such a high pH level.

## What is the pH of pure water?

7The pH of pure water is 7, the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. The hydrogen ion concentration equals the hydroxide ion concentration, and both equal 1 X 10-7 M.

## Is pH 14 a strong base?

Like strong acids, a strong base dissociates nearly completely in water; however, it releases hydroxide (OH-) ions rather than H+. Strong bases have very high pH values, usually about 12 to 14.

## Is pH more than 14 possible?

When a base, or alkaline, is dissolved in water, the pH will be greater than 7. A solution of a strong alkaline, such as sodium hydroxide, at concentration 1 mol dm−3, has a pH of 14. Mostly – measured pH values will lie in the range 0 to 14, though negative pH values and values above 14 are entirely possible.

## How is pH calculated?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+]. … Example: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10-5 M?

## What is the pH value of solution?

pH of Aqueous Solutions If the pH of a solution is less than 7, the solution is called acidic; if the pH is about 7, the solution is neutral; if the pH is greater than 7, the solution is is called basic. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.

## 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!

## What food has the highest pH?

Here’s a list of vegetables and their pH levels:sauerkraut (pH: 3.30–3.60)cabbage (pH: 5.20–6.80)beets (pH: 5.30–6.60)corn (pH: 5.90–7.50)mushrooms (pH: 6.00–6.70)broccoli (pH: 6.30-6.85)collard greens (pH: 6.50–7.50)

## What is the maximum value of pH of a solution?

14Minimum value of pH solution is 0 and maximum value of pH solution is 14. The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is neutral.

## Why is pH Max 14?

For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar. … 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.

## What is a high 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). … It is neither acidic nor basic, and has a pH of 7.0. Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline.

## What is the world’s strongest acid?

carboraneThe carborane superacids may be considered the world’s strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride. Carborane has a pH value of -18.

## Is pH of 22 possible?

The pH scale typically stretches from zero to 14, passing through a neutral pH7 (freshly distilled water). … But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.

## What happens if the pH is too high?

An increase in acidity causes pH levels to fall. An increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it’s called acidosis. When your blood is too alkaline, it is called alkalosis.

## What acid can kill you?

Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. Its chemical formula is HF. It is a very dangerous acid, being very corrosive and extremely toxic. It can dissolve glass to make hexafluorosilicic acid.

## Can Stomach acid dissolve gold?

No. Stomach acid is hydrochloric acid, and hydrochloric acid is unable to react with any of the less reactive metals, including gold, silver, copper, and platinum on its own.

## Is a pH of 14 dangerous?

In terms of pH hydrofluoric acid is considered a weak acid – it does not fully ionize in water – but it is extremely dangerous because of how corrosive it is. … Liquid Drain Cleaner: pH = 14.
