Identify the following salts as neutral, acidic, or basic.

1. NH4ClO4
2. NH4CN
3. LiF
4. KCN
5. LiNO3
6. NH4Br
7. SrBr2

1)NH4ClO4: acidic

2)NH4CN: basic

3)LiF: basic

4)KCN: basic

5)LiNO3: neutral

6)NH4Br: acidic

7)SrBr2: neutral

Explanation:

Salt is an ionic compound formed by the neutralization reaction between an acid and a base.The cation of base and anion from an acid combines to form a salt while H+ from acid and OH- from base forms water.

1)NH4Cl4: is an acidic salt formed from neutralization reaction between strong acid and a weak base.

2)NH4CN: is a basic salt formed from neutralization reaction between weak acid and weak base.

3)LiF: basic salt formed from neutralization reaction between strong acid and strong base.

4)KCN: basic salt formed from neutralization reaction between weak acid and strong base.

5)LiNO3: neutral salt formed from neutralization reaction between strong acid and strong base.

6)NH4Br: acidic salt formed from neutralization reaction between strong acid and weak base.

7)SrBr2: neutral acid formed from neutralization reaction between

strong acid and strong base.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
