Question

Which has the highest ph ch3coonh4 na2co3 nh4cl nano3?

Answer 1

Answer:

N a2 Co 3

Explanation:

Because ph value of these all are

• Ch3coonh4=7
• N a2 Co 3 =above 7
• Nh4cl= 4.6 to 6
• Nano3= 7

Answer 2

$Na_2CO_3$ has highest pH as it is basic.

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.

When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.

$CH_3COONH_4$:  neutral, as it is formed from the combination of weak acid and weak base

$Na_2CO_3$:  basic, as it is formed from the combination of weak acid and strong base.

$NH_4Cl$:  acidic, as it is formed from the combination of strong acid and weak base.

$NaNO_3$:   neutral, as it is formed from the combination of strong acid and strong base.

Thus $Na_2CO_3$ has highest pH as it is basic.
