What is the basicity of HClO4?
question. Perchloric acid is a monobasic acid, that is the basicity of perchloric acid is 1.
What is the pH of 0.1 m HClO4?
pH = 1.1
In the case of 0.1 M HClO4 (pH = 1.1), which is the electrolyte most usually reported on the literature, the onset potential in the presence of bromide is significantly displaced to more negative potentials.
How do you find the pH of perchloric acid?
1 Answer
- We use the pH equation, which states that,
- pH=−log[H+]
- And so, the pH will be,
- pH=−log[0.075]
- ≈1.12.
How do you make 1m perchloric acid?
1 M Perchloric acid: 244252; MW 100.46; d = 1.664 (g/mL); 70% assay; 11.59 M) Add 8.6mL perchloric acid to 92.4 mL of distilled water and mix thoroughly.
What does 70% perchloric acid mean?
% refers to solution concentration in percentage and “(w/w)” refers to solute and solution amount given in grams (i.e., percent by weight). This means a 70% (w/w) Perchloric acid solution contains 70 g of HCLO4 per 100 g of solution. The density of 70% Perchloric acid solution is 1.68 g/ml at 25° C.
How do you calculate perchloric acid?
I use (X%*10)/MW formula to find out molarity from percent solution. In this case 60% perchloric acid is 60*10/100.46 = 5.97 M. Then you can just use the dilution formula for preparing your desired concentration.

to give 1 mole of Hydrochloric acid – HCl. Hence, the answer is – option (d) – the pH of 0.01 M solution of HCl is 2.
What is the molarity of perchloric acid?
Dilutions to Make a 1 Molar Solution
| Concentrated Reagent | Formula Weight1 | Molarity (M) |
|---|---|---|
| Hydrofluoric Acid (HF) | 20.006 | 28.9 |
| Nitric Acid (HNO3) | 63.013 | 15.6 |

Why is perchloric acid strong?
Perchloric acid (HClO4) is one of the strongest mineral acids. Hot and concentrated perchloric acid has powerful oxidizing and dehydrating properties, and it will react explosively with organic compounds.
How do you find the pH of HClO4?
What is 1M pH?
The pH of 1 M hydrochloric acid is zero. The reason is that pH is defined as negative 1 times the log base 10 of [H+], or the proton concentration in moles per liter. Chemistry.
What is the pH of a solution with H +] .01 m?
4
0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.
What is the meaning of 0.1 M solution of HCl?
Therefore, 8.3 ml of 37% HCl in 1000 ml water is required to prepare a 0.1M HCl solution.
How do you find the pH of hclo4?
What is the pH of a 1.0 M sodium acetate solution?
1 Answer. The pH of a 1.0 M sodium acetate solution is greater than 7.0.
What is the pH of a 0.1 M solution of sodium acetate?
Neglecting [H+], the mass balance equations give [CH3COO ] + [CH3COOH] = 0.1 [CH3COOH] = [OH ] + [HCO3 ] Without carbonic acid we get [CH3COOH] = [OH ] and [CH3COO ]=0.1; then[OH ]2 = 0.1×10 9.24 and pH = 8.9.
What are the hazards of perchloric acid?
its use should be avoided when possible. Perchloric acid is bought as a 70-72% solution (the dihydrate) and in this form it is simply an extremely corrosive liquid. Its major hazard, however, is the variety of ways it can be involved in explosions and fires. When the water concentration falls (due to distillation or addition of a dehydrating agent), the acid becomes an extremely strong
What are some uses of perchloric acid?

Why is phosphoric acid called triprotic acid?
Two common examples are carbonic acid (H 2 CO 3, which has two acidic protons and is therefore a diprotic acid) and phosphoric acid (H 3 PO 4, which has three acidic protons and is therefore a triprotic acid).
What is the balanced equation for phosphoric acid?
