You have an acid that dissociates partially in solution. Is this a strong or weak acid? Explain. Is the solution 1.0 \times 10_{-8} M HCl (aq) acidic, basic, or neutral? What will be the pH of a solution of weak base and w...
Classify each of the following as a strong acid, weak acid, strong base, or weak base. a. H2SO4 b. NaOH c. HI d. Ba(OH)2 Classify each of the following substances: KOH H2SO4 H2S KBr NH3 As strong acid, weak acid, strong...
A buffer solution is described as an aqueous solution composed of a weak base and its conjugate acid, or vice versa. This is used to maintain the pH range of a solution upon the addition of small amounts of acid or b...
When appropriate air―dried unfixed slide preparations are available, virtually all cases of HCL are found to contain at least some cells with strong, granular cytoplasmic tartrateresistant acid phosphatase positivity; weak staining is of no diagnostic utility. 【...

Hydrogen bromide is also a strong acid and is corrosive. 16.碘化氢是一种弱酸,但同样具有刺激性。 Hydrogen iodide is a weak acid but still has an irritating nature. 17.氢氟化物的沸点较低,易在室温下挥发。 Due to its low boiling point, hydrogen fluoride easily vaporizes at room temperature. ...
yellowing skin or eyes (jaundice), nausea, upper stomach pain, itching, unusual weakness or tired feeling, rapid weight gain, fever, chills, sore throat, body aches, flu symptoms, high potassium (slow heart rate, weak pulse, muscle weakness, tingly feeling), or angioedema (swelling). Angioede...
Hydrogen chloride feed gas enters at the top of the falling film absorber and flows co-currently with weak acid coming from the tails tower. The heat that is released from the solution as a result of the absorption process is removed by the cooling water flowing in the shell side of the ...
- Oxalic is toxic, but it produces no fumes, no smell, you can use it even inside. Unless you eat few spoonfuls or drink a liter of oxalic solution (very untasty), you are fine. Its very weak acid so no big issue with etching the skin, but because of its toxicity it's better ...
Data from a prespecified pool of adult patients from 8 short-term, placebo-controlled trials of dapagliflozin coadministered with metformin immediate-or extended-release was used to evaluate safety. This pool included several add-on trials (metformin alone and in combination with a dipeptidyl peptidase...
