yes
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
Magma with low viscosity
Mt. Pinatubo is known to have explosive eruptions. The violence of an eruption is influenced by the amount of dissolved gas in the magma, the viscosity of the magma, and the presence of water or other fluids. If the magma has high gas content, is highly viscous, and interacts with water, it can lead to a more violent eruption.

Colima produces explosive eruptions, characterized by the sudden release of gas, ash, and magma. These eruptions can generate pyroclastic flows, lava flows, and volcanic ash plumes.
The most likely combination to result in a violent volcanic eruption is the presence of highly viscous magma (such as rhyolitic or andesitic magma) and a large amount of dissolved gas (particularly water vapor and carbon dioxide). These conditions can lead to a buildup of pressure within the magma chamber, causing a violent and explosive eruption. Other factors such as the presence of a vent or conduit for the magma to reach the surface and the structural weakness or faults in the volcano can also contribute to the severity of the eruption.
Rhyolitic magma. Boom! Basaltic magma is its exact opposite, while andesitic magma is in between the two.
An explosive eruption occurs if magma is high in gas content and viscosity. The high gas content creates pressure within the magma chamber, leading to a violent release of energy when the eruption occurs. The high viscosity of the magma makes it more difficult for gases to escape, further increasing the explosiveness of the eruption.
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
