5. Allah SWT created the earth with abundance of minerals. A sample mineral contained only chloride, iodide and nitrate anions. A titration was carried out to determine the chloride and iodide content. Standardized silver nitrate was used as titrant, and a silver wire immersed in the solution was used to monitor the solution’s electrochemical potential as the precipitates formed. The concentration of the standardized silver nitrate solution was 0,1 M. The burette initial reading was 1.35 mL, and the volumes at the two end points were 12.75 ml and 40.95 mL. Given that the original sample was 0.5 g, what is the percentage difference between iodide and chloride in the sample? (Ksp AgCl = 1,78 x 10-10, AgI = 9,8x10-17), (Molar mass, g.mol-1 for I=126,9, Cl=35,55) (Note: please write the answer IN NUMBER, WITHOUT writing the unit)

8. pls help meEach unit of the pH scale represents a tenfold change in hydrogen ion concentration. What is the difference in hydrogen ion concentration between hydrochloric acid and a lemon? Thanks a lot
hydrogen ion concentration (H⁺) is greater in hydrochloric acid than a lemon with same concentration of both solutions
Weak acids (lemon has citric acid) partially ionize in water and give only a few hydrogen ions (H⁺), in the solution there molecules of acid and ions.
> HCL is more acidic than Lemon's concentration

10. 20.0 cm³ of hydrochloric acid is needed to neutralize completely 25.0 cm³ of 0.1 mol dm-3 sodium hydroxide solution in the conical flask. Calculate the molarity of the hydrochloric acid.
The molarity of the hydrochloric acid is 0,125 M
»EXPLANATION«In this case, you can use 2 ways to solve it: first, stoichiometrically, by first making a balanced reaction and then using moles to calculate molarity (mol/L); and second, which is simpler. Use the formula below:
Va × Ma × a = Vb × Mb × b
where Va is the volume of the acid, Ma is the molarity of the acid, and a is the valence of the acid; the same goes for bases.
Hydrochloric acid (HCl) and sodium hydroxide (NaOH) each have one valence. So, the calculation:
Va × Ma × a = Vb × Mb × b
20.0 cm³ × Ma × 1 = 25.0 cm³ × 0,1 M
20 cm³ × Ma × 1 = 2,5 mmol
Ma = 0,125 M

13. 400 cm of sodium hydroxide solution 0.5 mol dm 3 is used to neutralise 100 cm of hydrochloric acid solution as shown in the reaction below. NaOH(aq) + HCl(aq) - NaCl(aq) + H2O(1) 4 What is the concentration of the hydrochloric acid solution? A 0.100 mol dm3 С 1.00 mol dm3 B 0.200 mol dm3 D 2.00 mol dm3
Jawaban:
D. 2,00 mol/dm³
Penjelasan:
V NaOH = 400 cm³ = 0,4 dm³
M NaOH = 0,5 mol/dm³ or 0,5 M
V HCl = 100 cm³ = 0,1 dm³
Reaction:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
Ask: concentration of HCl?
answer:
neutralise equation is:
Va x Ma x a = Vb x Mb x b
0,1 dm³ x Ma x 1 = 0,4 dm³ x 0,5 M x 1
0,1 dm³ x Ma = 0,2 mol
Ma = 0,2 mol / 0,1 dm³ = 2,00 M or 2,00 mol/dm³
nb:
cm³ = ml
dm³ = L

17. calculate the number of moles of hydrochloric acid required to react exactly with 4.15 g sodium carbonate
Reaksinya jika HCl dalam bentuk larutan dengan padatan Na2CO3 :
2HCl + Na2CO3 ==> H2CO3 + 2 NaCl
Reaksinya jika HCl dalam bentuk cair dengan padatan Na2CO3 :
2HCl + Na2CO3 ==> 2NaCl + H2O +CO2
n Na2CO3 = m Na2CO3 ÷ Mr Na2CO3 = 4,15 g÷ 106 g/mol = 0,04 mol
n HCl = (koefisien HCl÷koefisien Na2CO3)× n Na2CO3 = (2÷1)×0,4 mol
= 0,8 mol
Jadi jumlah HCl yang dibutuhkan adalah 0,8 mol

20. An example of a 0.6025 g of chloride salt was dissolved in water and its chloride was precipitated with excess silver nitrate. The silver chloride precipitate is filtered, washed, dried and weighed 0.7134 g. calculate% Cl in the example
Jawaban:
kita anggap sampelnya adalah XCl
XCl + AgNO3 --> AgCl + XNO3
berat AgCl adalah 0,7134 gram
berat Cl di AgCl = berat Cl di XCl
berat Cl di AgCl = (Ar Ag / Mr AgCl) x berat AgCl
berat Cl di AgCl = (108 / 143,5) x 0,7134
berat Cl di AgCl = 0,53691 gr
% Cl pada sampel = (massa Cl / massa sampel) x 100
% Cl pada sampel = (0,53691 / 0,6025) x 100
% Cl pada sampel = 89,11%
