K_b= 5.4×10⁻⁴

c= 0.02M

Then, α= (K_b /c)^1/2

α= (5.4×10⁻⁴ / 2 x 10^-2)^1/2 =0.1643

(CH₃)₂NH+H₂O ↔ (CH₃)₂NH⁺₂+OH^-

[ (CH₃)₂NH] = 0.02 – x ≈ 0.02

[ (CH₃)₂NH⁺₂] = x

[OH^-] = 0.1 + x

≈ 0.1

Now, K_b= [ (CH3)2NH+2] [OH−]/ [ (CH3)2NH] = (x × 0.1) / (0.025).

x = 1.08 x 10^-4

% of dimethylamine ionised = (1.08 x 10^-4) x (100 / 0.02) = 0.54%

IPFC Academy offers certification courses such as CMA USA, CIA USA, CPA USA and ACCA UK.The college prepares students through its Online Live Classes. Students with work experience can enroll to these programmes.

pH = 9.95,  

pOH = 14 – pH = 14 − 9.95 = 4.05
[OH⁻] = 10^−pOH = 10^−4.05 = 8.913 × 10⁻⁵

Codeine + H₂? O? Codeine^H+ + OH⁻

The ionization constant,  K_b? = [CodeineH⁺] [OH⁻] / [codeine]?

= [ (8.913×10⁻⁵)× (8.913×10⁻⁵)] / 5×10⁻³

= 1.588×10⁻⁶.

pK_b? = −log (1.588×10⁻⁶)

= 5.8

Once the M.Tech selection process is completed at SRMU AP, students with admission offers are required to pay a part of the tuition fees to secure their seat. As per official sources, the total tuition fees for M.Tech courses amount to INR 3 lakh.

Note: The above-mentioned fee is as per the official sources. However, it is indicative and subject to change.

The domain-wise average package received during IIM Rohtak placements 2025 is presented below:

H⁺] = cα = 0.1 × 0.132 = 0.0132M

pH = −log [H⁺] = −log0.0132

= 1.88

The acid dissociation constant is 

 K_a? = cα²? / (1−α) = 0.1 × (0.132)² / (1−0.132)

= 2.01×10⁻³.

pK_a? = −logK_a? = −log (2.01×10⁻³) ≈ 2.7

The highest package offered during IIM Rohtak placements over the past three years is presented below:

(a) 0.003 M HCl
[H_3? O⁺] = [HCl] = 0.003M

 pH = −log [H⁺] = −log (3.0×10⁻³) = 2.523

(b) 0.005 M NaOH
[OH⁻] = [NaOH] = 0.005M
[H⁺] = K_w? / [OH⁻]? = 10⁻¹⁴/ 0.005? =2×10⁻¹²

pH= −log [H⁺]=−log (2×10⁻¹²)=11.699

(c) 0.002M HBr
[H⁺]= [HBr]=0.002

pH= −log [H⁺]=−log0.002=2.699

(d) 0.002M KOH
[OH⁻]= [KOH]=0.002M
[H⁺]= Kw / [OH⁻]? =10⁻¹⁴ / 0.002? =5×10⁻¹²

pH= −log [H⁺]=−log (5×10⁻¹²)=11.301
