The pKa range of the compound is typically between 0 and 14.
Yes, if the pH is less than the pKa, the compound will be protonated.
Yes, a compound is considered acidic if it has a low pKa value.
The pKa value of a compound when it is protonated refers to the pH at which half of the compound is in its protonated form and half is in its deprotonated form.
A compound with a low pKa value is a stronger base. The lower the pKa value, the more likely the compound is to accept a proton and act as a base in a chemical reaction.
The pKa value of a compound is a measure of its acidity. A higher pKa value indicates a weaker acid and therefore a stronger base. So, a compound with a high pKa value is more basic because it is less likely to donate a proton and more likely to accept one.

The pKa value of a compound can be determined by measuring the pH at which the compound is half ionized and half unionized. This can be done through titration experiments or using specialized equipment like a pH meter. The pKa value indicates the strength of the compound as an acid or a base.
the organic compound three kind normal, acid and basic compound for acid compound the pKa from 3 to 5, normal pKa around 7 and basic compound more than 7 also you can know the kind of organic compound from structure that you can see acidic or basic grope like carboxylic acid or amine.
pKa and pKb are measures of the strength of acids and bases, respectively. pKa measures the acidity of a compound, while pKb measures the basicity. In acid-base chemistry, pKa and pKb are related by the equation pKa pKb 14. This means that as the pKa of a compound increases, its pKb decreases, and vice versa.
The effective pH range for a sodium phosphate buffer with a pKa value of 2.15 is typically 1.15 to 3.15. This range is optimal for buffering capacity at pH levels around the pKa value, ensuring stability and effectiveness for biological or chemical processes requiring a specific pH environment. Beyond this range, the buffer may not efficiently maintain the desired pH.
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
Cholic acid is a bile acid, a white crystalline substance insoluble in water, with a pKa of about 5.5. Urea is an organic compound with the chemical formula (NH2)2CO often found in the urine of animals, with a pKa of about 0.18.
Thiourea is a weakly acidic compound with a pKa value of around 10.5.
