Explanation:

According to Arrhenius concept :

An acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water. For example hydrochloric acid, sulfuric acid. etc.

$HA(aq)+H_2O\rightarrow A^-(aq)+H_3O^+(aq)$

A base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water .For example : sodium hydroxide , calcium hydroxide etc.

$BOH(aq)\rightarrow B^+(aq)+OH^-(aq)$

A 46.2 mL,0.568 M calcium nitrate solution is mixed with 80.5mL of 1.396M calcium nitrate solution.Calculate tge concentration o

Ne4ueva [31]

Answer:

1.09 M

Explanation:

Let's define the equation that will be used to calculate the final concentration of the resultant calcium nitrate solution. In order to calculate it, we need to find the total number of moles of calcium nitrate and divide by the total volume of the resultant solution:

$c=\frac{n}{V}$

This equation firstly helps us find the number of moles of calcium nitrate. Multiplying molarity by volume will yield the moles. Adding the moles from the first component to the second component will provide us with the total number of moles of calcium nitrate:

$n_{Ca(NO_3)_2}=46.2 mL\cdot0.568 M+80.5 mL\cdot1.396 M=138.62 mmol$
