## Description

This MCP server provides precise chemical calculations for buffer solutions. It allows AI agents to determine the exact ratio of conjugate base to weak acid needed for a target pH using `get_required_ratio`. It can predict how much the pH will change after adding a strong acid or base via `calculate_ph_shift`, and measure the resistance to pH changes using `get_buffer_capacity`. For complex systems, `simulate_polyprotic_buffer` handles acids with multiple dissociation constants, accounting for sequential dissociation steps.

## Tools

### calculate_ph_shift
Predicts the new pH of an existing buffer after the addition of a strong acid or a strong base

### get_buffer_capacity
Calculates the resistance of the buffer to pH changes at a specific pH

### get_required_ratio
Determines the ratio of conjugate base to weak acid needed to achieve a specific target pH

### simulate_polyprotic_buffer
Handles complex buffer calculations for acids with multiple dissociation constants

## Prompt Examples

**Prompt:** 
```
What ratio of acetate to acetic acid do I need for a pH of 4.76 if the pKa is 4.76?
```

**Response:** 
```
The required molar ratio of conjugate base to weak acid is 1:1.
```

**Prompt:** 
```
If I add 0.01 moles of HCl to a buffer with 0.1M acetic acid and 0.1M sodium acetate (pKa 4.76), what is the new pH?
```

**Response:** 
```
The new pH will be approximately 4.56.
```

**Prompt:** 
```
Calculate the buffer capacity for a solution with 0.1M acid, 0.1M base, and pKa 5.0 at pH 5.0.
```

**Response:** 
```
The buffer capacity at pH 5.0 is 0.10.
```

## Frequently Asked Questions

**How do I calculate the required ratio for a specific pH?**
You can use the `get_required_ratio` tool by providing the pKa of the acid and your desired target pH.

**Can this tool handle polyprotic acids like phosphoric acid?**
Yes, the `simulate_polyprotic_buffer` tool is specifically designed to handle acids with multiple dissociation constants.

**How is buffer capacity measured?**
Use the `get_buffer_capacity` tool, which requires the acid concentration, base concentration, pKa, and the current pH.
