The carboxylic acid turns blue litmus red. Because the hydroxyl group present in -COOH is far acidic than in alcohol.

Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic (i.e. alkaline) conditions. The pigment in blue litmus reacts with H+ ions and changes chemically so the bonds are ‘tuned’ to reflect a longer wavelength of light to appear red to our eyes.

CO2​ gas is acidic, hence the acidic property turns blue litmus red.

The carbonyl group, a carbon-oxygen double bond, is the key structure in these classes of organic molecules: Aldehydes contain at least one hydrogen atom attached to the carbonyl carbon atom, ketones contain two carbon groups attached to the carbonyl carbon atom, carboxylic acids contain a hydroxyl group attached to …

Therefore, the answer is – option (a) – an alcohol and a carboxylic acid can be experimentally distinguished by Sodium bicarbonate test. Additional Information: Sodium bicarbonate test is also known as sodium hydrogen-carbonate test. Carboxylic acid (like any other acid) turns blue litmus red.

Take 1ml of given compound in a dry test tube. Add a few drops of ceric ammonium nitrate reagent and shake the solution well. Observe the solution. If red precipitate appears then the presence of alcoholic group is conformed.

Ethanol

The initial test to identify alcohols is to take the neutral liquid, free of water and add solid phosphorus(V) chloride. A a burst of acidic steamy hydrogen chloride fumes indicate the presence of an alcohol. Subsequent tests are needed to distinguish between alcohol classifications.

with PCl5 The reaction between phosphorus pentachloride and an alcohol can be used as a diagnostic test for alcohols as white, steamy fumes are observed which turn damp litmus paper red.

Alcohols react with liquid phosphorus(III) chloride (also called phosphorus trichloride) to make chloroalkanes. Solid phosphorus(V) chloride (phosphorus pentachloride) reacts violently with alcohols at room temperature, producing clouds of hydrogen chloride gas.

Phosphorus trichloride (phosphorus chloride, PCl3) is a colorless fuming liquid that reacts violently with water to liberate phosphoric acid and hydrogen chloride (HCL) gas. PCl3 is a strong oxidizer and will readily react with many organic compounds.

PCl3 as an electrophile.

Any spillage of phosphorus trichloride should be neutralized with copious amounts of water. In the event of cloud formation, use a water curtain, e.g. call the fire brigade. If insufficient water is added, phosphine can be formed.

NVMe (Non-Volatile Memory Express) is an interface protocol built especially for Solid State Drives (SSDs). NVMe works with PCI Express (PCIe) to transfer data to and from SSDs. SSDs have a clear advantage with faster access through the PCIe serial bus standard. …

Download and install CPU-Z. Once installed, open it and head to the ‘Mainboard’ tab. Under the “Graphic Interface” tab, you’ll see what type of PCIe connection you have, along with its link width. Look for ‘x16’ in ‘Link Width’ and ‘PCI-Express 3.0’ under ‘Version’.

A PCI slot is a built-in slot on a device that allows for the attachment of various hardware components such as network cards, modems, sound cards, disk controllers and other peripherals. It was often a component of traditional do-it-yourself (DIY) desktop computer design.

PCI Express Theoretical Max Bandwidth

Yes, you can put a PCIe X16 card in a X8 slot. Electrically, there is no difference between the two as they both receive the same 75 W of power from the motherboard.
