What are optical substances?
Optically active substances are those substances that rotate the plane of polarized light to the left or right.
Does water posses optical activity?
Yes, water can exhibit optical activity if impurities or dissolved substances are present. Pure water itself is not optically active, but impurities such as dissolved minerals, gases, or organic compounds can cause it to rotate the plane of polarized light.
Is chirality synonymus with optical activity?
Chirality and optical activity are related concepts, but they are not synonymous. Chirality refers to the geometric property of a molecule having a non-superimposable mirror image, typically due to the presence of a chiral center. Optical activity, on the other hand, is the ability of chiral molecules to rotate the plane of polarized light. While all optically active substances are chiral, not all chiral substances exhibit optical activity under certain conditions, such as when they are present in racemic mixtures.
What is the difference between optical isomer and optically active isomer?
Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.
Difference between active and passive optical component?
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
Does active transport move substances against the concentration gradient?
Yes, active transport moves substances against the concentration gradient.
Does active transport move substances against their concentration gradient?
Yes, active transport moves substances against their concentration gradient.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
What substances are in snuff?
The active ingredient is nicotine.
What is the term for not chemically active?
The term is "inert." Inert substances do not react chemically with other substances.
During active transport substances move from regions of what?
in active transport, where do molecules always go
