In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...
(chemistry) The amount of solute in a solution measured in suitable units (e.g., parts per million (ppm)) Strength Operative effectiveness or potency The strength of the drug. Concentration The matching game pelmanism. Strength Intensity, as of sound or light The strength of the wind. Concen...
What is an analytical concentration in analytical chemistry? Types of Concentrations: The concentration of a substance can be measured in several ways. It may be grams over liters (gram concentration), moles over liters (molar concentration), or mililiters per 100 mililiters (volume concentration...
What is the solubility of M(OH)2 in pure water? Ksp = 7.45 x 10^-18 Define solubility and concentration. Find the solubility of AgI in 2.0 M NH3. (Ksp of AgI = 8.3 10^-17 and Kf of Ag(NH3)2^+ = 1.7 10^7) Calculate the molar solubility of CuX (Ksp = 1.27 x 10-36) in...
In potentiometric titration, the concentration-dependent potential (mV) of a solution is measured against a reference potential. In practice, potentiometric titration bears similarity to a redox reaction. However, potential is measured across the analyte — typically an electrolyte solution — using refer...
of primers, and not due to the lack of reagents, which are in excess. There should be enough nucleotides, polymerase and other reagents left for the amplification of the less abundant genes. In a primer limited multiplex reaction, the Ct values for both genes wi...
For example the nicotine concentrates or actual ejuice containing nicotine can have their nicotine concentration measured by titration. Although you may not want to talk about ejuice and nicotine in the classroom unless you are allowed to do a lecture warning about negative effect of nicotine on ...
The rate law for a reaction is measured experimentally. If the rate is dependent on a specific species, A, the rate law is described as rate=k[A]n where k is the rate constant for the reaction, A is the molar concentration of the specific reaction species and n is the reaction order...
What is mL in physical chemistry? Physical chemistry: Physical chemistry is the field of study that marries physics and chemistry. It is often used to predict and describe the behavior of characteristics of substances, especially those that are unable to be measured or observed directly. ...
