Chemists define the acidity or alkalinity of a substance according to the formula "pH \( =-\log \left[\mathrm{H}^{+}\right]^{\prime} \) where \( \left[\mathrm{H}^{+}\right] \)is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic; solutions with a pH of 7 (such as pure water) are neutral. a) Suppose that you test apple juice and find that the hydrogen ion concentration is \( \left[\mathrm{H}^{+}\right]=0.0003 \). Find the pH value and determine whether the juice is basic or acidic. (Round or truncate the pH to the thousandth. Don't forget to answer the entire question.)

To find the pH value of the apple juice, we can use the formula provided: \[ \text{pH} = -\log \left[\mathrm{H}^{+}\right]. \] Given that \( \left[\mathrm{H}^{+}\right] = 0.0003 \) moles per liter, we can compute the pH: \[ \text{pH} = -\log(0.0003) \approx 3.522. \] Since the pH value is less than 7, we conclude that the apple juice is acidic. So, the pH of the apple juice is approximately 3.522, confirming its acidic nature! For a fun fact, did you know that many fruits and vegetables have naturally high acidity levels? For instance, citrus fruits like lemons and limes can have pH values below 3! By understanding pH, you can become a flavor explorer, discovering why that tangy taste tickles your taste buds! And when it comes to testing the acidity at home, using pH strips or meters can be a fantastic hands-on experiment. You can test various liquids in your kitchen like vinegar, soda, or even soap! Just remember, keep the test fun and safe—some of those substances may not be ideal for tasting! Experimenting with pH can ignite a curiosity for chemistry in your daily life!
