Is KHP corrosive?
Is KHP corrosive?
Potassium hydrogen phthalate, often called simply KHP, is an acidic salt compound. It forms white powder, colorless crystals, a colorless solution, and an ionic solid that is the monopotassium salt of phthalic acid….Potassium hydrogen phthalate.

Is KHP a strong acid?
Potassium hydrogen phthalate ( KHP ) has the molecular formula C8H5KO4 and is known to be a weak acid. Because the concentration of water is presumed constant and therefore not included in the expression, the equilibrium constant for this reaction is called acid dissociation constant, Ka .
Where can I find MSDS sheets?
To obtain SDS, get them from the manufacturer. They may be sent with the chemical order (paper copy or e-mail attachment). Otherwise, go to the manufacturer’s website and download it or request a copy.
Is potassium acid phthalate the same as potassium hydrogen phthalate?
Phenolphthalein Indicator is most commonly used in titrations where KHP is used as an acidimetric standard to standardize solutions of bases….Potassium Hydrogen Phthalate.

Can KHP go down the drain?
Thanks in advance for any help! No chemicals of any kind go down our drains. Everything goes out as chemical waste through appropriate disposal paths. Check your appropriate local-state-federal laws for your area.
What is KHP used for?
Potassium hydrogen phthalate (KHP) is a widely used primary standard (functioning as a mono- protic acid) for acid/base titrations. The titration curve in Table 1 shows an example of using KHP to determine NaOH concentration (a process called standardization).
What is the Ka of hydrochloric acid?
1.3 * 106
Ka | Acid | |
---|---|---|
1.0 * 109 | Hydrobromic acid | HBr |
1.3 * 106 | Hydrochloric acid | HCl |
1.0 * 103 | Sulfuric acid | H2SO4 |
2.4 * 101 | Nitric acid | HNO3 |
Is HCl a strong acid?
HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.
How do I find MSDS products?
Go on the website of the manufacturer of the product. Once you are on the manufacturer’s website, see if they have a section where they make their MSDSs/SDSs available to the public. You can then search through their MSDSs/SDSs and locate the one for your product.
How do you make a TOC standard solution?
To prepare a 1000mgC/l Total Organic Carbon (TOC) standard solution, use one of the following: Potassium Hydrogen Phthalate, C8H5KO4, 2.13g (99.9% purity) in one liter of deionised water. Water solubility: 80 g/L at 20°C. Acetic acid, C2H4O2, 2.51g (99.8% purity) in one liter of deionised water.
Can you pour hydrochloric acid down the sink?
The acid can ruin the bacterial process in the septic system and drain field. Never dispose of hydrochloric acids or any other acids or bases on the ground, in a storm drain or in a gutter, because they can contaminate groundwater, surface water and drinking water supplies.
