2. Mix solutions to prepare a sulfate salt with ph 7.Options to choose from and their unmixed pH:H2CO3= pH 4Ca(OH)2= pH 12H2SO4= pH 2NaOH= pH 12HCl= pH 2NH3= pH 10
SODIUM SULFATE with ph 7.
Salts are formed when an acid reacts with a base during a neutralization reaction.
When a strong acid and a weak base reacts, it leads to the formation of acidic salt.When a strong base and weak acid reacts, it leads to the formation of basic salt.When a strong acid and strong base or weak acid and weak base reacts, it leads to the formation of neutral salts.Sodium sulfate is a neutral salt, it creates aqueous solutions with a pH of 7. The neutrality of such solutions is due to the fact that Na2SO4 is produced from a strong acid (sulfuric acid) and a strong base (sodium hydroxide).
Hence, a neutral salt and water is formed as products.
Acidic salts are those which are formed by combination of strong acid and a weak base and have acidic pH of less than 7.
Basic salts are those which are formed by combination of weak acid and a strong base and have basic pH of more than 7.
Neutral salts are those which are formed by combination of weak acid and a weak base or by combination of strong acid and a strong base and have neutral pH equal to 7.

a. pOH = 2, pH = 12
b. pOH = 5, pH = 9
c. pH = 2, pOH = 12
d. pH =8, pOH = 6
e. pH = 7.4, pOH = 6.6
Step by Step explanation:
example we take number a. pOH = 2, pH =
The formula is: pH + pOH = 14
pH = 14 - pOH
pH = 14 - 2
pH = 12
b. pOH = 5, pH =
pH = 14 - pOH
pH = 9
c. pH = 2, pOH =
The same formula: pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 2
d. pH =8, pOH =
pOH = 14 - pH
pOH = 6
e. pH = 7.4, pOH =
pOH = 14 - pH
pOH = 6.6

18. What is the nature of substance if the pH is less than 7? pH is greater than 7? and pH is equal to 7?
Answer:
A substance with a pH less than 7 is ACIDIC, greater than 7 is ALKALI and equal to 7 is NEUTRAL.
stay safe :)
Answer:pH is less than 7 - acidic
pH is greater than 7 - basic/alkaline
pH is equal to 7 - neutral
Explanation:pH stands for potential hydrogen
In chemistry, pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
Remember:・pH lower than 7 - acidic
・pH greater than 7 - basic
・pH equal to 7 - neutral
Examples:Acidic Substances
- Citrus fruits (Oranges, Lemons, Limes)
- Soft drinks
- Vinegar
- Yogurt
- Jelly
Basic Substances
- Baking soda
- Toothpaste
- Bleach
- Washing Powder
- Ammonia
Neutral Substances
- Water
- Table salt
- Sugar solution
- Cooking oil
- Sugar
Ways to know the acidity and alkalinity/basicity of a substance:Litmus paper
- A strip of paper that is chemically treated with a dye named litmus. This strip is placed in the liquid whose pH is being determined. The use of litmus paper, which is red at any pH less than 5 and blue at any pH greater than 8, allows an inspector to determine only whether a solution is acidic or basic.
・red = acidic
・blue = basic
・no reaction = neutral
Titration
- The total alkalinity analysis involves titration. In this test, titration is the addition of small, precise quantities of sulfuric acid (the reagent) to the sample until the sample reaches a certain pH (known as an endpoint). The amount of acid used corresponds to the total alkalinity of the sample.
19. which of the following is the most acidic? a.an acid with a pH of 0 b.an acid with a pH of 2 c.an acid with a pH of 4 d.an acid with a pH of 6

20. 2. Which is the most acidic? A. pH 1 B. pH 7 C. pH 8 D. pH 14
Answer:
A
Explanation:
The pH scale ranges from 0 to 14. The pH of a solution is a measure of its acidity or alkalinity (base). You have probably used litmus paper, paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid or base (alkalinity) exists in a solution. You might have even used some to make sure the water in an outdoor swimming pool is properly treated.
21. why is the pH of rainwater 5.6. Is this pH acidic or basic
Acidic. Always remember: Less than 7 is acidic while greater than 7 is base
It's acidic, because since its pH level is <7.00, and when you taste an acid always tastes sour at low levels.
