The rule that applies in this evaluation is that in addition or subtraction operations, the answer (total/difference) should not be more accurate than the least accurate term. In this case, the number with least sig fig is 2.70 or 4.21. The answer here is 9.66 x10-3.

the ph of a solution of HCl in water is found to be 2.50. what volume of water would you add to 1.00L of this solution to raise

morpeh [17]

<u>Answer:</u>

<em>To raise the pH of the solution to 3.10 we have to add 2.34 L of water.</em>

<u>Explanation:</u>

<em>Given that the pH of the solution of HCl in water is 2.5.</em> Here the solution’s pH is changing from 2.5 to 3.10 which means the acidic nature of the solution is decreasing here on dilution. $[H^+]$ ions contribute to a solution’s acidic nature and $[OH^-]$ contribute to a solution’s basic nature.

The equation connecting the concentration of $[H^+]$ and pH of a solution is pH= $-log[H^+]$

<em> $[H^+]= 10^(^-^p^H^)$ $[H^+]= 10^(^-^2^.^5^)=0.00316$ </em>

<em>When the pH is $3.1 [H^+ ]= 10^(^-^3^.^1^)=0.000794$ </em>

<em>On dilution the concentration of a solution decreases and volume increases.</em>

<em> $M_1 V_1 = M_2 V_2$ </em>

<em> $0.00316 \times 1 = 0.000794 \times V_2$ </em>

<em> $V_2 = \frac{(0.00316 \times 1)}{0.000794} =3.24$ </em>

<em>Volume of water to be added $=3.24-1$ </em>

<em> $=2.24L$ </em>

Use scientific notation to express 3.76 mg in grams

makkiz [27]

There are 1000 mg in 1 gram.
3.76/1000 = 0.00376

10^-3 = 0.001

0.001 x 3.76 = 0.00376

Answer is
3.76 x 10^-3
