What is the pH value of KOH n 1000 solution?
10−11.
What is the pH of a 1.0 10 2 M KOH solution?
So pH of the 1.0 * 10-2 mol-1 KOH is 12.
What will be the pH of a 10 8 M HCl solution?
The pH of 10-8 M of HCl is less than 7.
What is the pH of a 1 nm HCl solution?
In case of HCl (very strong acid) you can assume that it is 100\% ionised in H2O. Therefore, pH= -log (molarity). Hi, as professor Thomas Proft said pH= -log[H3O+], thus HCl 1M has a pH=-1, however pH has been defined between 0 and 14, according to the water constant (pK=14).
What is the formula for Koh?
The chemical formula KOH stands for potassium hydroxide. The first letter, K, is the symbol for the element potassium; the next letter, O, stands for oxygen; and the letter H stands for hydrogen. One oxygen atom bonded to a single hydrogen atom is a hydroxide ion.
What is the purpose of using KOH?
The primary purpose of the KOH test is the differential diagnosis of infections produced by dermatophytes and Candida albicans from other skin disorders. Dermatophytes are a type of fungus that invade the top layer of the skin, hair, or nails, and produce an infection commonly known as ringworm, technically known as tinea.
Is Koh a strong or weak acid?
K+ is the conjugate acid of the strong base KOH. NO3- is the conjugate base of the strong acid HNO3. A very weak acid or base will not affect the pH of an aqueous solution. If neither ion of the salt causes the pH to increase or decrease, the solution will be neutral.
What is the purpose of a KOH test?
Definition. The KOH test takes its name from the chemical formula for potassium hydroxide (KOH), which is the substance used in the test. The test, which is also called a potassium hydroxide preparation, is done to rapidly diagnose fungal infections of the hair, skin, or nails.
