What is the pH value of 0.1 m HCl?
1
Strong Acids and Bases pH of 0.1 M HCl = 1, etc.
What is 1M in chemistry?
A 1 molar (1 M) solution contains 1 mole per litre (1 mol/l) a 1 millimolar (1 mM) solution contains 1 millimole per litre (1 mmol/l) Note: mol and moles mean the same thing (an amount) and moles/litre (long. winded but correct) is a concentration and can be expressed as mol/l, or mol.l-1, or.
What is the pH of 0.15 M HCl?
Nam D. Truong-Son N. I get 1.82 .
What is 1M concentration?
In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol⋅dm−3 in SI unit. A solution with a concentration of 1 mol/L is said to be 1 molar, commonly designated as 1 M.
What is the difference between 1M solution and 1M solution?
If one mole of solute is dissolved in 1 liter of solution, then the molarity of the solution is said to be 1M. If one mole of solute is dissolved in 1 kg of solvent, then the molality of solution is said to be 1 m.
What is the meaning of ‘1m of HCl’?
1 M HCl. HCl stands for hydrochloric acid. It is a strong acid. The molar mass of hydrochloric acid is calculated as under. The molar mass of hydrochloric acid= Mass of H + Mass of Cl So 1M HCl would be 36.5 g of hydrochloric acid dissolved in 1 litre of solvent.
What is the density of 1m HCl?
HCl, also known as hydrochloric acid, maintains a density of 1.49 grams per cubic centimeter when measured at standard temperature and pressure values of 68 degrees Fahrenheit and 1 standard atmosphere unit. The density also depends on the molarity of the solution, related to its concentration.
How do you calculate the pH of HCl?
To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH.
What is the pH of 0 . 1 M HCl?
A 0.1 M HCl solution has 0.1 M H3O+ and a pH = 1, whereas a 0.1 M acetic acid solution (CH3COOH) has 0.001 M H3O+ (since it is only 1\% dissociated) and a pH = 3. The Keq of an acid is a measure of the strength of an acid.
