What is the pH of CH3COOH?
When acetic acid solution is diluted by ten times, it’s pH value is increased by 0.5. As an example, 0.1 mol dm-3 acetic acid is diluted upto 0.01 mol dm-3, pH value is increased from 2.87 to 3.37….pH values of acetic acid at different concentrations.
| Concentration of acetic acid (mol dm-3) | pH |
|---|---|
| 0.001 | 3.87 |
| 1 | 2.37 |
What pH is CH3COONa?
Sodium acetate has a pH of 7.
What will be the pH change when 0.01 moles of CH3COONa?
The pH change when 0.01 moles of CH3COONa is added in 1 litre 0.02 M CH3COOH solution is equal to 1.25. pKa of acetic acid is equal to 4.8 . So, pH of 0.02 M acetic acid comes out to be 3.25. Therefore, change in pH=1.25.
Is CH3COONa acidic or basic?
Solid sodium acetate (CH3COONa) is a salt, not an acid or a base. It is a salt formed from a weak acid (CH3COOH) and a strong base ( NaOH). However, on hydrolysis of CH3COONa in water, the resultant solution is basic.
What is CH3COOH CH3COONa?
CH3COOH is a weak acid, while CH3COO- is a weak base (the Na+ is not important to the buffer, it can be considered a spectator ion). The pH of this buffer depends on the [CH3COOH] and the [CH3COO-].
What is the empirical formula of CH3COOH?
Explanation: CH3COOH can be written as C2H4O2. An empirical formula represents the lowest whole number ratio of elements in a compound. The subscripts in the formula C2H4O2 can be reduced to the simplest whole number ratio by dividing the subscripts in the molecular formula by 2. The empirical formula of acetic acid is CH2O.
What is the equivalent weight of CH3COOH?
Equivalent weight of acetic acid. The molecular weight of CH3COOH=60.05g/mol, C has a weight of. 12.01 (×2)=24.02gram, and H has a wt of 1.01 (×4)=4.04grams And O has a wt of 16 (×2)=32g grams; 24.02+4.04+32=28.06+ 32=60.06 grams .
What is the chemical formula for CH3COOH?
Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colorless liquid organic compound with the chemical formula CH3COOH (also written as CH3CO2H or C2H4O2).
What is the structure of CH3COOH?
CH3COOH is an organic compound and the COOH is the carboxylic acid functional group. If you recognize this the Lewis structure is much easier to draw. In CH3COOH you should memorize what the COOH functional group looks like. Remember that Hydrogen only needs 2 valence electrons for a full outer shell.
