Question

a) Beer: $$ \mathrm{pH}=4.9 $$ $$ \left[\mathrm{H}^{+}ight]=\square 	imes 10^{\square} \mathrm{M} $$ (b) Water: $$ \mathrm{pH}=6.8 $$ $$ \left[\mathrm{H}^{+}ight]=\square 	imes 10 \square \mathrm{M} $$

To find the concentration of hydrogen ions $$\left[\mathrm{H}^{+}\right]$$ from the pH values, we can use the formula:

$$
\left[\mathrm{H}^{+}\right] = 10^{-\mathrm{pH}}
$$

### (a) Beer: $$ \mathrm{pH}=4.9 $$

Using the formula:

$$
\left[\mathrm{H}^{+}\right] = 10^{-4.9}
$$

Calculating $$10^{-4.9}$$:

$$
10^{-4.9} \approx 1.26 \times 10^{-5} \, \mathrm{M}
$$

So, we can fill in the blanks:

$$
\left[\mathrm{H}^{+}\right] = 1.26 \times 10^{-5} \, \mathrm{M}
$$

### (b) Water: $$ \mathrm{pH}=6.8 $$

Using the formula:

$$
\left[\mathrm{H}^{+}\right] = 10^{-6.8}
$$

Calculating $$10^{-6.8}$$:

$$
10^{-6.8} \approx 1.58 \times 10^{-7} \, \mathrm{M}
$$

So, we can fill in the blanks:

$$
\left[\mathrm{H}^{+}\right] = 1.58 \times 10^{-7} \, \mathrm{M}
$$

### Summary:

(a) Beer: $$ \left[\mathrm{H}^{+}\right] = 1.26 \times 10^{-5} \, \mathrm{M} $$

(b) Water: $$ \left[\mathrm{H}^{+}\right] = 1.58 \times 10^{-7} \, \mathrm{M} $$
