The given statement is False.

Some acids like acetic acid and tartaric acid can be tasted.

Organic acids, such as acetic, citric, malic, and fumaric acids in fruits and vegetables, and tartaric acid in wine, contribute significantly to the sour flavor of foods and beverages. Many inorganic acids taste sour in dilute solutions.

Tartaric acid is fairly water soluble and has a pronounced tart flavor. Tartaric acid is present naturally in grapes and bananas and has been shown to improve the flavor of grape and lime-flavored beverages. Tartaric acid may aid in the treatment of glucose intolerance and digestion.

Acetic acid is a colorless liquid having a sour flavor. Although it is most frequently associated with vinegar, this acid has a wide range of different applications in a variety of industries. Acetic acid is a colorless liquid that is composed of chemical compounds.

Given a sample of three unknown solids, we would be able to deduce which are ionic solids by their melting and boiling points, conductivity in water, and the insulation they provide.

Therefore, we can find the ionic solids amongst the samples by testing their melting and boiling points, conductivity in water, and the insulation they provide, given that each of these should provide high values to indicate an ionic solid.

There are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles in the substance by its molecular mass.

However, given that the number of molecules in calcium hydroxide is 4.07 x 10¹⁵molecules, we need to calculate the number of moles in Ca(OH)2 as follows:

no. of moles of Ca(OH)2 = 4.07 x 10¹⁵ ÷ 6.02 × 10²³

no. of moles = 0.676 × 10-⁸

no. of moles = 6.76 × 10-⁹ moles.

Molar mass of Ca(OH)2 = 74.093 g/mol

Mass of Ca(OH)2 = 74.093 × 6.76 × 10-⁹ moles

Mass = 5.01 × 10-⁷grams.

Therefore, there are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.

The systematic Iupac name for the internal alkyne is : 4-octyne

When only one type of carboxylic acid is made the internal alkyne will be symmetric and the compounds can be 3-hexane or 4-octyne but given that one of the reactants is propyl iodide. Therefore

The Internal alkyne will have an Iupac name 4-octyne

Hence we can conclude that the systematic Iupac name for the internal alkyne is 4-octyne

The formation of molecule can easily be shown by drawing Lewis dot structure. Since atom's Lewis dot structure has three dots. Therefore, in below given ways, we can have Lewis dot structure of CO.

Lewis dot structure is a way to represent the valence electron of an element in the form of dot. These are mainly beneficial in understanding the chemical formula of covalent compound.

Carbon contains four valence electrons, whereas oxygen has six. Carbon has five electrons but oxygen has seven electrons if just one link is established among carbon and oxygen atoms.

The solitary connection formed in between two atoms is insufficient to form an octet on every atom. A triple bond is required to finish the octet of the each atom in CO. The six electrons shared by these two atoms create a triple bond. The dipole moment arrow will point between carbon to oxygen.

Therefore,  in above given ways, we can have Lewis dot structure of CO.

What are the advantages of titration?

Titrimetric analysis commonly referred to as volumetric analysis offers distinct advantages over cumbersome gravimetric methods:

Speed of analysis.

Instantaneous completion of reactions.

Greater accuracy due to minimization of material loss involved in decanting, filtration, precipitation or similar operations.

Explanation:

Disadvantages

It is a destructive method often using up relatively large quantities of the substance being analysed.

It requires reactions to occur in a liquid phase, often the chemistry of interest will make this inappropriate.

It can produce significant amounts of chemical waste which has to be disposed of.
