Correct answer is (a) 100 mL of 0.1 M HCl +200 mL of 0.1 M NH 4 OH

Q. Which will make basic buffer?

$100 m L$ of $0.1 M H Cl + 200 m L$ of $0.1 MN H_{4} O H$

$100 m L o f 0.1 M H C I + 100 m L o f 0.1 M N a O H$

$50 m L o f 0.1 M N a O H + 25 m L o f 0.1 M C H_{3} COO H$

$100 m L o f 0.1 M C H_{3} COO H + 100 m L 0.1 MN a O H$

Correct answer is (a) $100 m L$ of $0.1 M H Cl + 200 m L$ of $0.1 MN H_{4} O H$

100mL of 0.1MHCl+200mL of 0.1MNH4​OH

100mLof0.1MHCI+100mLof0.1MNaOH

50mLof0.1MNaOH+25mLof0.1MCH3​COOH

100mLof0.1MCH3​COOH+100mL0.1MNaOH

Correct answer is (a) 100mL of 0.1MHCl+200mL of 0.1MNH4​OH

$100 m L$ of $0.1 M H Cl + 200 m L$ of $0.1 MN H_{4} O H$

$100 m L o f 0.1 M H C I + 100 m L o f 0.1 M N a O H$

$50 m L o f 0.1 M N a O H + 25 m L o f 0.1 M C H_{3} COO H$

$100 m L o f 0.1 M C H_{3} COO H + 100 m L 0.1 MN a O H$

Correct answer is (a) $100 m L$ of $0.1 M H Cl + 200 m L$ of $0.1 MN H_{4} O H$
