Explain why indicators are useful for measuring pH

Chemistry
1 answer:
ycow [4]2 years ago
8 0

Explanation:

pH indicators are weak acids that exist as natural dyes and indicate the concentration of H+ (H3O+) ions in a solution via color change. A pH value is determined from the negative logarithm of this concentration and is used to indicate the acidic, basic, or neutral character of the substance you are testing.

A conductor is distinguished from an insulator with the same number of atoms by the number of:_____.
Savatey [412]

A conductor is distinguished from an insulator with the same number of atoms by the number of nearly free electrons.

<h3>What are conductors and insulators?</h3>

Whether an object is made of conductive or nonconductive material affects how it behaves once it has been charged. Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.

A charge is swiftly dispersed across the full surface of the object if it is applied to it at a specific point. The motion of the electrons causes the distribution of charge. A charged object will constantly disperse its charge until the overall repulsive interactions between surplus electrons are minimized because conductors allow electrons to be moved from particle to particle.

Insulators, as opposed to conductors, are substances that prevent electrons from freely moving from one atom or molecule to another.

Describe the properties of alkaline earth metals. Based on their electronic arrangement, explain whether they can exist alone in
zheka24 [161]

Answer: all i know about alkaline metals is he alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure.

All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge.

All of the alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope.

Magnesium and calcium are ubiquitous and essential to all known living organisms.
