Answer :

Certainly! Let's solve the problem step-by-step:

### Problem Statement:
We are given:
- 1 ml of 1 M HCl
- 10 ml of 1 M NaOH

We need to determine:
1. The amount of salt (NaCl) formed.
2. The amount of HCl left.
3. The amount of NaOH left.

### Step-by-Step Solution:

1. Convert the volumes from milliliters to liters:

For HCl:
[tex]\[ \text{Volume of HCl in Liters} = \frac{1 \text{ ml}}{1000} = 0.001 \text{ L} \][/tex]

For NaOH:
[tex]\[ \text{Volume of NaOH in Liters} = \frac{10 \text{ ml}}{1000} = 0.01 \text{ L} \][/tex]

2. Calculate the moles of HCl and NaOH:

Moles of HCl (using Molarity [tex]\(M = \frac{\text{moles}}{\text{L}}\)[/tex]):
[tex]\[ \text{Moles of HCl} = 1 \text{ M} \times 0.001 \text{ L} = 0.001 \text{ moles} \][/tex]

Moles of NaOH:
[tex]\[ \text{Moles of NaOH} = 1 \text{ M} \times 0.01 \text{ L} = 0.01 \text{ moles} \][/tex]

3. Determine the limiting reactant and the amount of product formed:

The neutralization reaction between HCl and NaOH is:
[tex]\[ \text{HCl} + \text{NaOH} \rightarrow \text{NaCl} + \text{H}_2\text{O} \][/tex]

From the stoichiometry of the reaction, 1 mole of HCl neutralizes 1 mole of NaOH to form 1 mole of NaCl.

We compare the moles of HCl and NaOH:
- Moles of HCl = 0.001 moles
- Moles of NaOH = 0.01 moles

Since 0.001 moles of HCl are less than 0.01 moles of NaOH, HCl is the limiting reactant.

4. Calculate the amount of salt (NaCl) formed:

Since HCl is the limiting reactant, the moles of NaCl formed will be equal to the moles of HCl:
[tex]\[ \text{Moles of NaCl} = 0.001 \text{ moles} \][/tex]

5. Determine the remaining moles of reactants:

- HCl is the limiting reactant, and all of it reacts, so the remaining moles of HCl = 0.
- Since all 0.001 moles of HCl react, the moles of NaOH that react will also be 0.001 moles. Thus, the remaining moles of NaOH = 0.01 moles - 0.001 moles = 0.009 moles.

### Final Result:

- Moles of NaCl formed = 0.001 moles
- Remaining moles of HCl = 0 moles
- Remaining moles of NaOH = 0.009 moles

Therefore, when 1 ml of 1 M HCl is mixed with 10 ml of 1 M NaOH:
- The amount of salt (NaCl) formed is 0.001 moles.
- The amount of HCl left is 0 moles.
- The amount of NaOH left is 0.009 moles.
