You are so excited-your first summer job! You are a hot-tub maintenance assistant. You travel to homes, making sure the pH of th

eir hot-tub water is correct (between 7 and 7.6), and adjusting and cleaning when necessary. But before you get started, you need to answer the following questions. What is pH? What do you use to test it? Why would it be important to keep the pH of hot-tub water between 7 and 7.6?

Answer: well i guess we can say that  is a scale used to specify the acidity or basicity of an aqueous solution and it is important to keep ph of hot tub water between 7 and 7.6 because if it is not balanced the water  can negatively affect your tub.

Explanation:

pH is an extremely important chemical level to maintain in your spa's water chemistry. A high pH or a low pH will spell trouble for you and your spa. On the pH scale, a reading of 7.4-7.6 indicates perfectly balanced pH. Any number lower than 7.4 means that your water is now considered “acidic”.

Answer:

pH is a scale to measure the acidity or basicity of a substance such as water, it would be important to keep the pH of hot-tub water between 7 and 7.6 because if the acidity is too high, the walls of the hot-tub may be damaged, and if the pH is too low, the heating thing may get damaged.

How do you analyze chemical evidence?
Sever21 [200]
BIOLOGICAL & CHEMICAL EVIDENCE ANALYSIS
There are many different types of evidence that can be found at a crime scene. Physical evidence can be collected at the crime scene such as a murder weapon. Chemical evidence is any residue from liquids that such as poison and drugs. Biological evidence is when hair or skin from a persons body has been transferred to a physical surface and then be collected and tested.

This evidence can be used to find out what exactly happened at the scene of the crime, the history behind the crime and who was involved and could have committed it.

Our experts test and analyse many forms of evidence, which is vital when finding out the various incidences that happened at a crime scene.

Q8. The titration of 15.00 mL of HBr solution of unknown concentration requires 18.44 mL of a 0.100 M KOH solution to reach the
lara [203]

Answer: 0.123 M

Explanation:

According to the neutralization law:

n_1M_1V_1=n_2M_2V_2

where,

M_1 = molarity of HBr solution = ?

V_1 = volume of HBr solution = 15.00 ml

M_2 = molarity of KOH solution = 0.100 M

V_2 = volume of KOH solution = 18.44 ml

n_1 = valency of HBr = 1

n_2 = valency of KOH = 1

1\times M_1\times 15.00=1\times 0.100\times 18.44

M_1=0.123

Therefore, the concentration of the unknown HBr solution is 0.123 M
