2. 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

3. Ionic equation between calcium carbonate and an acid
Jawaban:
CaCO3 + HCl - Calcium Carbonate + Hydrochloric Acid.
Jawaban:
CaCO₃ (s) + 2HCl (aq) ---> CaCl₂ (aq) + H₂O (l) + CO₂ (g)
Discussion
The chemical formula for calcium carbonate is CaCO₃ which is formed from Ca²⁺ ions and CO₃²⁻ ions. Meanwhile, hydrochloric acid solution has the chemical formula HCl.
Correction questions
The correct reaction product is a solution of chloride, water and carbon dioxide gas, according to the following equation:
CaCO₃ (s) + HCl ---> CaCl₂ + H₂O + CO₂ (not yet equal)
Balance the Cl atoms
CaCO₃ (s) + 2HCl (aq) ---> CaCl₂ (aq) + H₂O (l) + CO₂ (g) (already equivalent)
While the reaction that produces sodium sulfate and water is:
2NaOH (aq) + H₂SO₄ (aq) ---> Na₂SO₄ (aq) + 2H₂O (l)
4. which of these compounds is not an electrolyte? a. sulphuric acid b. copper(II) chloride c. ammonium chloride d. carbon tetrachloride e. potassium hydroxide

Senyawa tersebut memiliki ikatan kovalen, bukan ion
5. Which of the following chemicals is a nonelectrolyte?a. molten naphthalenab. sodium hydroxide solutionc. aqueous sulfuric acid solutiond. aqueous ethanoic acid solutione. aqueous potassium iodide solution
The First thing that you must knew about Electrolyte Solution, Have the Criteria:
- The Solution that Perfect Ionized
- Strong Acid or alkali (have strong electrolyte) and weak Acid or alkali (have Weak Elektrolytes)
- Salt Solution (NaCl, KCl, and any others)
I thing Molten Napthalena Is the best Answer, Napthalena as an Organic coumpund has a Stabilized structur, so dificult to ionized.
I Hope that answer your question...

10. 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

11. 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
12. why is calcium hydroxide formula written as ca(oh)2
Jawaban:
Cause Calsium Hydroxide is from
2 element
Ca=Calsium
OH=Hydroxide
Hydroxide = is from a element basa
sebab calsium hidroksida
berasal dari 2 gabungan campuran dari
Unsur calsium dan unsur hidroksida
dan jika digabung maka akan menghasilkan calsium hidroksida
nahh sifat basa yang ada di calsium hidroksida dapat menetralkan larutan acid atau asam

15. find the volume of sodium hydroxide 0.1 M to neutralize 20 ml of sulfate acid 0.2M
Jawab :
Volume natrium hidroksida (NaOH) 0,1 M yang dibutuhkan untuk menetralkan 20 mL asam sulfat (H₂SO₄) 0,2 M adalah 40 mL.
Penyelesaian Soal :
Diketahui : [NaOH] = 0,1 M
[H₂SO₄] = 0,2 M
V H₂SO₄ = 20 mL
Ditanya : V NaOH ?
Jawab :
V₁ × M₁ = V₂ × M₂
20 mL × 0,2 M = V₂ × 0,1 M
V₂ = (20 mL × 0,2 M) / 0,1 M
V₂ = 4/ 0,1 mL
V₂ = 40 mL
∴ Kesimpulan banyaknya volume NaOH adalah 40 mL.
Pembahasan :
Pengertian Molaritas (M)
Konsentrasi merupakan jumlah zat terlarut yang ada terhadap jumlah pelarut tertentu atau terhadap jumlah larutan tertentu. (diasumsikan zat terlarut berwujud cair atau padat, sedangkan pelarutnya berwujud cair) Konsentrasi dapat diungkapkan dengan beragam cara, salah satunya yang paling sering dipakai, dan memang akan kita gunakan sekarang ini adalah Molaritas (M), atau konsentrasi molar. Molaritas adalah jumlah mol terlarut setiap liter larutan. Atau bias diungkapkan dengan rumus:
M = n/V
Keterangan : M = konsentrasi zat
n = mol zat terlarut
V = volume larutan (L)
Pengenceran
Proses pengenceran adalah proses yang dilakukan dengan mencampurkan pelarut yang lebih ukurannya dari suatu zat yang dilarutkannya. engenceran pada prinsipnya hanya menambahkan pelarut saja, sehingga jumlah mol zat terlarut sebelum pengenceran sama dengan jumlah mol zat terlarut sesudah pengenceran. Dengan kata lain jumlah mmol zat terlarut sebelum pengenceran sama dengan jumlah mmol zat terlarut sesudah penegenceran atau jumlah massa zat terlarut sebelum pengenceran sama dengan jumlah massa zat terlarut sesudah pengenceran.
Rumus :
V₁ × M₁ = V₂ × M₂
Keterangan :
M₁ = Molaritas larutan sebelum pelarutan/pengenceran
V₁ = Volume larutan sebelum pelarutan/pengenceran
M₂ = Molaritas larutan sesudah pelarutan/pengenceran
V₂ = Volume Molaritas larutan sesudah pelarutan/pengenceran
