Chemical formula. C 8 H 5 K O 4: Molar mass: 204.222 g·mol −1 ... Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound.
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2]
56.1 g/mol is the molecular weight of KOH, W oil is the mass of the sample in grams. The normality (N) of titrant is calculated as: = Where W KHP is the mass (g) of potassium hydrogen phthalate (KHP) in 50 ml of KHP standard solution,
General chemical structure of orthophthalates. (R and R' are general placeholders.) Phthalates (US: / ˈ θ æ l eɪ t s / UK: / ˈ θ ɑː l eɪ t s ˌ ˈ f θ æ l ɪ t s / [1] [2]), or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility ...
In organic chemistry, phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2 and structure HO(O)C−C 6 H 4 −C(O)OH.Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale.

The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Weight loss: “People do tend to lose some weight doing Dry January--on the order of three to four pounds,” says Carr, who cites a single reason: alcohol is “empty calories with no ...
Monopotassium phosphate can exist in several polymorphs.At room temperature it forms paraelectric crystals with tetragonal symmetry. Upon cooling to −150 °C (−238 °F) it transforms to a ferroelectric phase of orthorhombic symmetry, and the transition temperature shifts up to −50 °C (−58 °F) when hydrogen is replaced by deuterium.
