This is fairly true.
In our bodies we have receptors constantly monitoring the level of the CO2 in our blood. When the level of CO2 rises, these receptors (called chemo-receptors) will register this, and signal the breathing center to increase rate of breathing.
What does this have to do with acidity you ask?
In our blood we have buffer systems, which are designed to minimize the change in pH done our blood by different waste products of metabolism. The main buffersystem is called the bicarbonate buffersystem:
CO2 + H2O <----> H2CO3 (carbonic acid) <---> H+ + CO3- (unbalanced)
The reaction is catalyzed by the enzyme carbonic anhydrase.
From the above equation you can deduct two things:
a) If you ADD CO2 to the equation, more H+ will eventually be produced and this will diminish the pH of the blood (pH = -log([H+])).
b) If you REMOVE CO2 from the equation, the reverse happens and less H+ is produced. This will raise the pH of the blood.
This is why the chemoreceptors register blood CO2 levels. Actually, what they are measuring is the pH of the blood. If they register too low a pH, they can signal the ventilation center in the brain to increase breathing, and thereby remove more CO2 from the body, and raise the pH.
The body uses this to combat conditions in which the pH of the body is too low. An example of this could be the state of diabetic ketoacidosis. This condition, not uncommon amongst diabetics, is characterized by increased acid production and thereby a lower blood pH.
The body responds to this threat by increasing ventilation (increased breathing) thereby removing CO2 from the blood and raising the pH. By these means the condition is compensated.
Normal blood pH ranges are: 7,35 - 7,45.

What happens to the breathing rate if blood concentration of oxygen decreases?
If the blood concentration of oxygen decreases, the body's chemoreceptors detect this change and send signals to the brain to increase the breathing rate. This helps to bring in more oxygen and expel carbon dioxide to maintain the body's overall oxygen levels.
How does Ph regulate breathing?
The pH level in the blood is a major regulator of breathing through the medulla oblongata in the brain. An increase in CO2 leads to a drop in blood pH, causing the brain to signal an increase in breathing rate to expel excess CO2 and restore pH balance. Alternatively, a decrease in CO2 leads to a rise in blood pH, causing the brain to signal a decrease in breathing rate to retain CO2 and maintain balance.
What organ regulates breathing rate?
The brainstem, particularly the medulla oblongata, regulates the breathing rate by monitoring levels of carbon dioxide and pH in the blood. This area helps control the diaphragm and intercostal muscles to adjust breathing in response to the body's needs.
How does Carbon Dioxide help the environment?
Carbon dioxide is necessary to maintaining the breathing rate in humans. When oxygen is utilized, the waste (carbon dioxide) is transported in the blood as dissolved bicarbonate. However, the presence of CO2 (carbon dioxide) in the blood causes it to become more acidic. Chemoreceptors in the blood monitor blood acidity and report to the the medulla area of the brain. If the chemoreceptors and the medulla evaluate that the acidity is too high, the medulla will instruct the intercostal muscles (muscles in between rib bones) and the diaphragm to increase the breathing rate. This is how CO2 regulates breathing rate and is necessary to our bodies.
When activated the breathing control centers increase the rate of nerve impulses to the via the?
When activated, the breathing control centers increase the rate of nerve impulses to the diaphragm and intercostal muscles. This causes these respiratory muscles to contract and expand the thoracic cavity, allowing air to flow into the lungs. By adjusting the rate and depth of breathing, the body can regulate oxygen and carbon dioxide levels in the blood.
What organs control your breathin and your pulse rate?
Your lungs control your breathing and your heart controls your pulse rate.
What hormones control breathing rate?
The adrenal glands raise blood sugar and increase the heartrate and respiratory rate. These changes make you best able to respond to environmental stresses.
What substance that increases heart rate and blood pressure and breathing rate in an emergency?
epinephrine

What factors control breathing rate?
Breathing rate increases when: -The respiratory center senses high CO2 levels and high H+ (hydrogen ion) concentration (controls pH). -Carbonic Acid/Bicarbonate Buffer System: CO2+H2O<->H2CO3(carbonic acid)<->H(+)+HCO3- -There are low blood O2 levels (sensed by chemo-receptors in certain blood vessels) -Emotions, fear, and pain can also increase breathing rate
