Why would you need a locating agent in an experiment to separate amino acids by chromatography
Nadusha1986 [10]

A locating agent is needed in an experiment to separate amino acids by chromatography as it helps to analyze colorless substances on paper.

<h3>What is chromatography?</h3>

Chromatography is an analytical method frequently used to separate a chemical mixture into its components, allowing for in-depth analysis of each component.

There are many different types of chromatography including liquid, gas, ion-exchange, and affinity chromatography, but they all use the same basic principle.

<h3>What is the use of a locating agent in Chromatography?</h3>

In paper chromatography, colorless compounds are examined using a locating agent.

It is a chemical that combines with colorless substances to produce colorful compounds that are easy to see for analysis. Ninhydrin spray is an example of a locating agent of this type.

Thus, a locating agent is used in an experiment to separate amino acids by chromatography as it helps in determining colorless substances on paper.

Balancing Al+ Agcl, i have problems with this so help!!!
EleoNora [17]

Answer:

Al  + 3AgCl  →  AlCl₃  + 3Ag

Explanation:

The given equation is:  

      Al  + AgCl  →  

We are to find the product and hence balance the equation. This problem is a simple single replacement reaction.

By virtue of this, Aluminum will displace Ag from the solution:

                       Al  + AgCl  →  AlCl₃  + Ag

    We then balance the equation:

                        Al  + 3AgCl  →  AlCl₃  + 3Ag
