Using Table J

Oxidation - Reduction Reactions

If iron is left uncovered in an area that is wet or damp, It will rust very quickly, often in a few days.

​

Iron Rusts Easily

Silver and Gold Jewelry is passed down through generations because they stay pure and shiny for hundreds of years

​

Silver and Gold stays beautiful

Over the years scientists have studied elements to

​determine how reactive they are. They arranged these elements on a chart based on their reactivity

​Some metals are very reactive while others are not

This table shows elements based on their reactivity. It is arranged by decreasing chemical activity

​

Reference Table J

Multiple Choice

Which metal is more reactive than calcium?

• magnesium

• potassium

• silver

• aluminum

Multiple Choice

True of False: Nickel is more reactive than Silver.

• True

• False

In a chemical reaction, a more active metal (higher up on Table J) will replace a less active metal when placed in an aqueous solution containing the ion of the less active metal.

​

Reference Table J

Mg(s) + Cu(NO₃)₂(aq)→Mg(NO₃)₂(aq) + Cu(s)

​

Think of a Single replacement reaction

On the Regents exam, we will use the activity series to determine whether a redox reaction is spontaneous. (will the reaction happen?)

​

Table J

A spontaneous reaction is a reaction that proceeds on its own without the addition of energy.

Spontaneous - reaction will happen

Not spontaneous - reaction will not happen

​

Copy in your notebooks

A spontaneous reaction will occur if the element un the reaction is above the element found in the compound compound on Table J

​

Copy in your notebooks

Mg(s) + Cu(NO₃)₂(aq)→Mg(NO₃)₂(aq) + Cu(s)

​

This reaction is spontaneous beacuse Mg ia above Cu on the Table

Multiple Choice

A mixture contains cobalt metal, copper metal, and tin metal. This mixture is mixed with nickel nitrate. Which metals, if any, will react? 

• Copper only

• Tin only

• Cobalt only

• All 3

Multiple Choice

Will silver react with magnesium chloride solution?

• Yes

• No

Multiple Choice

What  will be the result of the following:

 Li + NaF ->

• Li will replace F

• Na will replace F

• Li will replace Na

• no reaction will occur

Multiple Choice

Based on the activity series, which metal could X represent in the reaction below?

X + Ca (NO₃)₂ --> Ca + X (NO₃)₂

• Ba

• Mg

• Fe

• Zn

Cl₂(g) + 2NaBr(aq)→2NaCl(aq) + Br₂(l)

​

This reaction is spontaneous beacause Cl is above Br on the Table

Multiple Choice

Based on the activity series, will this reaction occur?

Br₂ (l) + KI (aq) →

• Yes

• No

Multiple Choice

What  will be the result of the following: 

Br₂ + NaF ->

• bromine will replace Na

• Br will replace F

• Na will replace Br

• no reaction will occur

Metals found above H₂ are more active than hydrogen. Therefore, they will replace the H ib a compound (or aqueous solutions)

Multiple Choice

Based on the activity series, will this reaction occur?

Ni (s) + H₂O (l) →

• Yes

• No

Multiple Choice

Based on the activity series, will this reaction occur?

Au (s) + HCl (l) →

• Yes

• No

Multiple Choice

Based on the activity series, will this reaction occur?

Cu (s) + HCl (aq) →

• Yes

• No
