18. 2. If lime juice has a pH of 1.7. What is the concentration of hydrogen ions (inmol/L) in lime juice to the nearest hundredth? Use the formula pH = -log (H+)
Answer:
0.02 mol/L
Explanation:
Given: pH = 1.7
Required: [H+]
Equation: pH = -log [H+]
Solution:
Take the antilog of both sides
[H+] = antilog(-pH)
Antilog(-pH) is equal to 10^-pH. Therefore
[H+] = 10^-pH
Solve for [H+]
[H+] = 10^-1.7
Answer: [H+] = 0.02 mol/L

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.

25. given pH=-log [H+] for calculating the hydrogen ion concentration.If lime juice has a pH of 1.7,what will be the representation in logarithmic form?
Answer:
In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,
− pH = log [H+] ,
[H+] = 10−pH,
by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of "Solution A" is,
[H+] = 10−5.6 ≈ 0.0000025 = 2.51 × 10−6 M.
We can always check our solution by computing −log (2.5 × 10−6)
