Answer:

Is the shampoo basic or acidic in nature? How can you know?

The shampoo by nature is of basic pH.

Explanation:

Since the basic shampoo weakens the hair by breaking the disulfide bonds of the keratin of the hair, it is sought to slightly acidify adding small flakes of various materials, for example, glycol distearate.

The shampoos hardly have the pH indicated, the most common is to see shampoo with balanced or neutral pH (pH 7). To know the pH of the shampoo you can buy pH measuring strips. A pH between 5.5 and 7 is correct.

<u>Answer:</u> The molarity of barium hydroxide solution is 0.118 M.

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $HClO_4$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is $Ba(OH)_2$

We are given:

$n_1=1\\M_1=0.102M\\V_1=24.0mL\\n_2=2\\M_2=?M\\V_2=10.3mL$

Putting values in above equation, we get:

$1\times 0.102\times 24.0=2\times M_2\times 10.3\\\\M_2=0.118M$

Hence, the molarity of $Ba(OH)_2$ solution will be 0.118 M.

I'm having trouble with this one. At the very least, they both purify water. If I'm not mistaken, distillation is part of the process of purifying water.
Really sorry, I hope I helped at least a little! If you have any other questions I might be able to answer better, let me know..
