What is the pH of a 0.1 M solution of HF?
We will calculate the pH of an aqueous solution which was made up as 0.1 molar HF.
log[H3O+] = -3 + 0.90 = – 2.10 and pH = 2.10.
This solution is so acidic that we can neglect any contribution from ionization of the water..
Is NaCl a base or acid?
A salt that is derived from the reaction of a strong acid with a strong base forms a solution that has a pH of 7. An example is sodium chloride, formed from the neutralization of HCl by NaOH. A solution of NaCl in water has no acidic or basic properties, since neither ion is capable of hydrolyzing.
Is Na2SO4 acidic or basic?
Sodium sulphate (Na2SO4) is formed by a reaction between sodium hydroxide and sulphuric acid which are strong base and acid, respectively. Thus, it a neutral salt with a pH of 7.
What is the pH of a 1.0 M solution of HCl?
All Answers (16) 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).
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). … Remember what we mean by a weak acid or weak base. They simply do not ionize completely whereas a strong acid or base does.
What is the pH of 0.1 m?
Water and pH pH of 0.1 M HCl = 1, etc.
What is the pH of 0.1 m NaCl?
7Since NaCl is a salt of strong acid and a strong base it is a neutral salt it’s pH is 7.No matter what it’s concentration is..
What is the pH of a 0.5 M HF solution?
2Since, it is given that initial concentration of HF is 0.5 M. The reaction equation will be as follows. Hence, we can conclude that pH of given 0.5 m aqueous solution of HF is 2.
Is Na2CO3 a salt?
When dissolved in water, sodium carbonate forms carbonic acid and sodium hydroxide. As a strong base, sodium hydroxide neutralizes gastric acid thereby acting as an antacid. Sodium carbonate is an organic sodium salt and a carbonate salt.
How do I calculate pH?
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+].
What is the pH of Na2CO3?

Is Na2CO3 basic or acidic?
Na2CO3 is neither an acid nor a base. It is a salt. A salt in chemistry is formed by the reaction of an acid and a base. Now depending on the strength of the respective acid and base from which the salt is derived, it may be categorised as an acidic, basic or a neutral salt.
What is the pH of nh4cl?
4.6 to 6.02 NH4Cl + Na2CO3 → 2 NaCl + CO2 + H2O + 2 NH. A 5% by weight solution of ammonium chloride in water has a pH in the range 4.6 to 6.0. Some of ammonium chloride’s reactions with other chemicals are endothermic like its reaction with barium hydroxide and its dissolving in water.
Is NH4Cl acidic or basic?
It is denoted by the symbol NH4Cl and is in solid crystalline form in nature. This compound is a water-soluble salt of ammonia, and aqueous ammonium chloride is slightly acidic.
What is the pH of 0.1 m Naoh?
13NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. Therefore pH of 0.1 M NAOH solution is 13.
