What is the difference between isoelectric point and point of zero charge?

The isoelectric point (IEP) is only representative of the external surface charges of particles in solution, whereas the point of zero charge (PZC) varies in response to the net total (external and internal) surface charge of the particles.

At which pH the particles or molecules are negatively charged?

pH ~7
Negatively charged surfaces are surfaces with a negative charge at physiological conditions (pH ~7). Such surfaces possess point of zero charge (pzc, or pI) below pH 7. Positively charged surfaces have pzc higher than pH 7.

Is vinegar positive or negative?

An acid is a solution that has a higher concentration of positively charged hydrogen ions (H) than negatively charged hydroxide ions (OH). Common examples of acids are lemon juice and vinegar. A base has a higher concentration of OH ions. Common examples are baking soda and household ammonia.

What is the oxidation number of chlorine in Cl2?

The oxidation number of an element in any elementary substance is zero. For example, the oxidation number of chlorine in Cl2, phosphorus in P4, and sulfur in S8 is 0. 2. The oxidation number of an element in a monatomic ion is equal to the charge on that ion.

Which is the correct name for chlorine oxide?

chlorine chlorite, ClOClO, chlorine (I,III) oxide dichlorine trioxide , Cl 2 O 3 , chlorine (I,V) oxide dichlorine tetroxide, also known as chlorine perchlorate , ClOClO 3 , chlorine (I,VII) oxide

What is the melting point of chlorine dioxide hydrate?

Chlorine dioxide hydrate, frozen is an orange colored solid, appearing as a block of ice, with a faint odor of chlorine. It may only be shipped in the frozen state and then only by private or contract motor carrier. The melting point of the hydrate is around 30°F.
