**Answer:**

you are correct good luck

**Answer:**

1,4,2,3,8 there you go, I don't know if it is 100 percent correct

**Answer:**

<h2>7.04</h2>

**Explanation:**

The pH of a solution can be found by using the formula

From the question we have

We have the final answer as

<h3>7.04 </h3>

Hope this helps you

The **ph of the buffer solution** is 7.743.

**What is the Henderson-Hasselbalch Equation?**

The Henderson-Hasselbalch **equation **establishes a relationship between the** pKa and pH **of acids. When the concentration of the acid and its conjugate base and the associated **conjugate acid**, are known, the **pH of a buffer solution** can be determined with the use of this equation.

We** use Henderson-hasselbalch equation, **

**pH = pKa + log [Base] / [Acid]**

pKa = -log Ka = -log (3.0 x 10^-8) = 7.46

pH = 7.52 + log [0.250] / [0.150]

pH = 7.52+ 0.2227

**pH = 7.743**

Therefore,** the ph **of the solution is** 7.743.**
